Trigger Pull: The trigger pull on the Sig Sauer GSR Sigarms was about medium to hard but I have definitely experienced heavier trigger pulls on some guns. It is nice that the trigger is in the style of a 1911 and not your typical lever styled trigger. This may be one reason why the pull is a bit heavier on the GSR.

Accuracy: Accuracy was decent but not outstanding; I got around a 2.5 inch grouping from a 20 foot away free standing position, shooting just to the left and high on the target. I did find that I was able to zone in a bit better with the Cybergun GSR as I got used to the trigger. I also put the Cybergun Sig Sauer GSR through my Chrony Chronograph and got very close the manufacturers 397 claimed feet per second, actually starting off well above it and settling down to around the 370 FPS mark. My 8 shot averages on a new CO2 was actually 422 FPS.

Build Quality: Very good, this is an almost all metal gun with a few exceptions like the hammer, trigger, magazine release, slide catch and the outer barrel. Pretty much everything else is metal including the slide, frame, magazine, and even the grips. The finish is very good and the Cybergun GSR worked flawlessly for me.

Realism: The Cybergun Sig Sauer GSR is very close to the look, weight, and feel of the real GSR Sigarms! Even the 1911 style trigger was used and licensed trademarks on the slide. It would have been nice to have a single action trigger and a working slide to finish off the illusion but overall the GSR is a really nice copy of the real steel Sig Sauer GSR Sigarms firearm.


  • Excellent weight and very solid feeling gun.
  • Mostly Metal design.
  • Very Accurate Sig Sauer GSR Sigarms with licensing.
  • Nice high fps results close to manufacturers specifications.
  • Very affordable and good value for the money.
  • Lots of shots per CO2.
  • Nice sights with white dots front and back.
  • Magazine holds both the CO2 and BB's - always nice.
  • Recessed barrel for added realism.
  • True 1911 style trigger even though it is double action only.


  • Non-blowback and the slide do not move either.
  • The hammer is only for show and does not cock for single action shots.
  • Nonadjustable rear sights.
  • Trigger action is bit on the heavy side.

Comments: I ordered my Cybergun Sig Sauer GSR Sigarms with two other Cybergun pistols (The Jericho 941 and Sig Sauer SP2022), all of them in the lower and more affordable price point, the GSR is the heaviest out of the bunch, most likely because of the metal frame. For a relatively inexpensive BB gun you get a lot for your money, most importantly a very accurate reproduction of the real GSR Sigarms firearm! If you're a 1911 fan and want to pick up an airgun that won't set you back too much, then the Cybergun GSR would make a great choice with its heavy weight, full size drop out metal magazine, and true 1911 styled trigger.

Great bang for your buck

For $60 bucks you can't go wrong. Plastic frame but metal slide so feels solid and not cheap at all. Nice full size mag. Hits hard and is crazy accurate. I took my ASG STI One plinking and this gun afterwards. I gotta say this gun was noticeably more accurate. All in all like an awesome no frills version of the more expensive guns. I recommend it bigtime.
