This is first CO2 blowback, I had a TM GBB M9) The blowback is impressive compared to M9. Target acquisition is excellent, thanks to the white dot on the sights. Also the ambidextrous safety is a plus.
I would not recommend any 1911 for a person with small hands. Right handers with small hands (using one-handed grip) that want the press the slide release will have the stretch their thumb quite a bit to get to it. Two-hand grip is the way-to-go anyway, at least for me. Left-handers, pressing with your index finger is no problem.
The comments about the small hand shooters should not deter you from buying this pistol though, as it's more my personal taste.
Finally note, the MadBull Airsoft Whisper .45ACP Barrel Extension is a great addition to this pistol.
