Umarex SA177 BB Gun Repeater

Feel weight and realism

I would change the blow back system for sure, they should have made it real, (the blowback would put a bb in the chamber. all it is, is a co2 port facing backwards that meets up with a seal that is on the slide, so when you pull the trigger co2 puts a bb out the barrel and pushes back the slide from the back facing port. A little cheesy if you ask me. also the mag could have been designed better. the trigger pull is VERY hard.

My gun that I had purchased must have been very poorly made. The seal for the blowback right away broke, and fell off. I glued it back on and it sort of worked. Another thing is the magazine, the top metal spring loaded peice that keeps the bbs in until they enter the chaber quickly wore down, so my bbs would fly every where one I released the spring at the bottom. I had also tried to fix that with superglue but only lasted a short time. My trigger was EXTREMLY hard and not consisntant.

This is a very close feel to my Glock. I bought it specifically for that reason. I get close to a 100 or more shots out of one CO2. The sights are very good visibility on dark targets. The magazine is very easy and fast to load unlike other BB action pistols. Blowback is nice and strong.

Somehow get that trigger to be better. It is almost like a finger workout device! Luckily I think in some weird way it will help with a combat Glock trigger. I said I like the sights and I do, I just wish they would have made the front a fiber rod as well. The white plastic is a little lame. But I guess Glocks are normally three white dots. Also I wish the slide was a bit harder to rack. I think they get the blowback from the spring form the super heavy trigger and not necessarily the slide...hard to say.

If you have Glocks and want something to train with buy this. The trigger is really the only real deterrant and that can be dealt with. It shoots a lot with one CO2 and is fast and pain free to load. All in all a great value

Very , Very accurate,nice blowback,good power, more than 100 rounds for co2 cartridge.

Front sight

Slide lock after the last round, but the trigger still working.no spare mag available

i really like the fibre optic sights and the blowback action on this gun it is also a great replica of a real glock. and the rail allow for you to easily mount a flashlight or laser on it

the slide is a little rattly and the trigger pull is hard and long

great replica its also great for all the glock lovers out there

Very nice pistol for the money. I'm using it to practice markmanship for about $0.005 a shot instead of $0.40 per shot! Using this translates well to a real glock, minus the recoil.

The gun doesn't fit into standard Glock holsters, which is a disappointment. I have several holsters, even some for the larger G20, but this gun doesn't fit. My desire is to use this to practice "first shot" draw technique.

Punches right through a soup can. After about 20' the BB's often begin to curve, but this gun is excellent for up to 20'.

Clean smooth double action trigger pull. Really excellent magazine, doesn't let the bb's fall out, easily removed, kind of nice the slide stays back when mag empties. Accuracy is just ok but then it's not a rifled barrel for pellets and it's a short barrel.

blowback action is a waste of CO2 power. Modify the air gun such that the blowback action cocks the weapon and enables single action or simply eliminate it. Additionally, insertion of the magazine should release the slide rather than having to manually release the slide. The 'safety' insert or small trigger in the main trigger is useless/cosmetic, the air gun can be fired without depressing the little trigger...just eliminate it. Safety on the RHS is ok, I like the safety on the HPP which is on the left. Umarex needs to field a fully semi auto blowback with both single and double action.

This is a double-action only air gun...the website says this but the pyramyd air staff that answered my telephone request was unsure of whether the blowback action cocked the air gun...it most certainly does not.

THIS IS A GREAT GUN AND AT A GREAT PRICE GOT MINE IN THE MAIL TODAY PUT ABOUT 1000 BB'S THROUGH IT ALREADY AND QUIT A FEW CO2'S HAVEN'T HAD ANY PROBLEM LOVE THE GUN GOOD JOB UMAREX

i would get rid of the fake glock like saftey in the trigger it starts to hurt the finger a little bit after shooting about five mags non stop

Magazine holds great amount of ammo, accurate, all around fun. Everyone who fires it has loved it.

Nothing

Love the action when empty reacts like a real gun. The feel and look are great!

-strong blowback -highly visible sights -very efficient with gas (around 100 useful shots with a moderate rate of fire) -metal slide -accurate for a bb pistol -outer barrel sleeve has an inner diameter of 9mm -great value

The fake trigger safety does not function and it only makes the heavy trigger pull less comfortable. Even though it is trying to replicate the Glock series of pistols, I would remove it and make the trigger blade a single piece.

The front sight is not fiber optic, but it is still easy to pick up. Also, the slide does not serve any function other than to blowback and add recoil. It does not chamber a bb or cock the gun. The trigger pull is heavy due to the design of the pistol as the barrel also acts as the hammer. The inner barrel moves forward inside the barrel sleeve as you pull the trigger. As it moves forward, a bb is fed into the barrel and it slams back against the valve to fire.

Wow, the blow back, feel, weight and over all construction is unbelievable. If you didn't get reminded while loading its a BB pistol, you would think it was the real deal. Accuracy was very good straight out of the box at 25 ft. Sites are bright and easy to line up. It has also been helpful in training the Mrs. with what to expect on recoil.

Trigger pull at times is a bit much and tends to veer shots to the right a bit.

This product is traditional to the Umarex quality and value for its price.
