This pistol is a real miser when it comes to CO2! When we tested it, we routinely got 100 or more useful shots per 12-gram CO2 cartridge.

The official velocity of the SA177 air pistol is 380 fps. However, we tested it and found that it went as fast as 410 fps.

Things I liked:

Feel weight and realism

Things I would have changed:

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.

What others should know:

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.

Things I liked:

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.

Things I would have changed:

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.

What others should know:

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
