Not much at present.
Things I would have changed:I could not screw the handle into the bolt because of poor thread cutting. This was not a cross-thread event. The two pieces would NOT mate. No response from Pyramyd. Disappointed.

What others should know:Overall very pleased with the whole set up. I will be adding another one to my next one.

Steel is way better than plastic. Holds the barrel much better
Things I would have changed:That dang screw that sits to low that causes pellets to get jammed or go wonky when loading them. I know there are aftermarket solutions, but crossman should really fix this (Maybe they have, but just want to sell out all there old steel breaches?)
What others should know:It's heavier than the plastic, but I personally think that is a good thing.

Everything.
Things I would have changed:I would make this the factory installed breech and never, ever subject another customer to the worthless plastic breech that is the current standard.
What others should know:It is worth the upgrade.

Great product, but I do it consider this an upgrade it's more of a retro part in order to utilize optics. The plastic breech is good and has no problems loading pellets. But with the steel breech a washer must be used to raise the breech screw in order to eliminate the pellets from jamming. The paper washer is the way I fixed the pellet jamming problem. Also the paper washer cost nothing, just take your time and cut some hard paper and problem solved.
Things I would have changed:I would add some paper washers in the breech kit.
What others should know:Pellet jam occurs with this retro/upgrade.

This gives you the ability to mount optics on your 1377. It improves and already accurate pistol. I think it makes pumping the gun easier as it stiffens the overall barrel breech connection. The pistol feels a lot more robust.
Things I would have changed:The biggest issue with this kit is that breech screw hole. The pellet will hang up and requires a lot of work to load properly. Crosman has know about this issue forever and just cannot seem to figure out how to include a simple nylon washer/spacers (like 3 cents guys- come on!) I was frustrated that they cannot include a slightly longer rear mount screw so the original sight can be utilized. (ok another 3 cents- but I would have GLADLY paid an extra quarter for those parts!) The barrel grub screw is WAY too long for the 1377 application and my dovetail to Weaver adapter had to be mounted in a way to accommodate the grub screw sticking up (I am going to find a shorter one in my screw collection and replace it. Crosman put lock tight on every screw EXCEPT the bolt handle threads (the one screw that actually NEEDS locktite)
What others should know:This takes your 1377 from a cheap beginner pistol, to a serious contender. Yes it is expensive (taking the price of the gun to the $100 dollar range) but it makes a difference in what can be done. Be aware the directions are for the 22xx/23xx series and not really user friendly for the 13xx series. My transfer hort fell out and I had a Heck if a time figuring out which end went up (it only fits properly one way). You cannot reuse the stock sight as the included (and original screw are too short. The barrel band on the new version of the 1377 does not need to be loosened (it can't be loosened) and you need to remove the lower tube hammerspring retaining plug (and the spring will fall out). This is challenging to replace as you need to compress the spring and line up the cap holes AND start the screw! I'm not a beginner when it comes to airguns, but this took me about 45 minutes to complete (from removing the old breech to a completed project.

I fits and the steel barrel makes this 1377 pistol manageable. The plastic breech that was on the pistol was not very good at all.
Things I would have changed:Chromed breech would have made this perfect.
What others should know:Easy install took about 5-10 minutes

Has places to mount scope rings.
Things I would have changed:Rear sight doesn't match front blade width. Make rear sight viewing notch narrower. Peep sight was better.
What others should know:I needed to glue thin pieces of plastic to both sides of front sight blade to make it a closer match with rear sight notch.

Adds a dovetail and improves accuracy of an otherwise less than adequate Crosman 1377. The sights and accuracy of the 1377 are terrible out of the box. However, this kit fixes that but also requires you to get another sight because you can't remount the original (although I wouldn't want to anyway) and doesn't come with any rear sight. Now my 1377 is an accurate pellet firing machine.
Things I would have changed:I agree with former reviewers about the screw underneath the chamber. I fixed this problem by getting a pellet loader, which helps in other situations as well.
What others should know:Crosman should make a model with this already installed. If you're serious about hitting your target, this kit is required for the Crosman 1377.

The steel breech kit is easy to install and allows you to put a scope or red dot sight on your 1377. It is a nice upgrade from the plastic breech that comes with the gun.
Things I would have changed:My breech kit was from the latest batch and I found that the breech screw hole was too deep which caused pellets to jam when loading. I solved the problem by backing out the screw a couple of turns which raised it enough to allow the pellets to feed properly. This problem was the reason for 4 stars instead of 5 overall.
What others should know:I contacted Crosman and they said that my solution was what they recommended to resolve the problem.

I ordered two because I own 2 1377 pistols. I like the looks and feel plus it makes a world of difference in the way the pistol shoots. Very nice and I am happy even tho I had to make a couple supper thin washers for under the breech screw.
Things I would have changed:The breech screw hole is much to deep. Redesign the hole to where the screw will fit flush so the pellets will not jam.
What others should know:To get the pellets to slide in without hanging up, get some 4-48 x 1/4" button head screws with the 1/16" hex and then make a supper thin metal washer. Even for the button head screws to raise them up just a bit. The original 0.050" screws strip the heads out to easy. That is why you use the button head screws. Anyway, Keep filing the supper small washers to where the screw and washer fit perfect and it will work just fabulous. It's a lot more work but you will like the finished work.

Provides a solid base for mounting optics.
Things I would have changed:The breech screw is countersunk too far. When screw is installed there is a hole that the pellets cross over and get tilted. I am having to point the gun upward, place the skirt over the bolt and fiddle with it to get the pellet lined up properly with barrel. So it needs a filler of some sort in that space. For $40 I expected a more precise fit.
What others should know:Bolt seems to have a lot of play. The fit of my plastic breech was better with the exception of not having dovetail.

The steel breech has been a solid platform for the red dot that I mounted. The breech stabilized the barrel. Still, I was getting inconsistent target results and did not know if it was because of the red dot or the Crosman pellets I was using, purchased from Walmart. The types I purchased were Pointed, Destroyer, Hollow Point. More on this below.
Things I would have changed:Cannot think of anything to change.
What others should know:I'm using a Crosman 1377 indoors at 20 feet. The steel breech and an inexpensive red dot have given me a stable and reliable platform. The missing piece for me was finally getting reliable results from pellets. I ordered some Crosman Wad Cutters from Pyramid. That's the pellet that has been the missing link for my airgun. I am now very satisfied with the groupings that I'm seeing. If you are experiencing inconsistent results, try wad cutters. Now my question is: does Pyramid receive better quality Crosman pellets than does Walmart? There is an obvious difference in the performance of the pellets from these two merchants; however, I have never seen wad cutters at Walmart, so I haven't been able to compare exact types. Would like to hear a comment from Pyramid on this.

Steel, nice weight and good finish. Secures very nicely and was easy to install after some fiddling even without looking at instructions(do still look at instructions there's no reason not to).
Things I would have changed:Blue loctite on the bolt handle threads but you can do it yourself quite easy and loctite is always good to have around anyways, it'll just come loose after working the action a few times(or maybe I'm just rough).
What others should know:This with the stock makes for a very accurate little plinker.
