That's what I don't like about 1911 .22's. The feel like an airsoft gun.
My GSG certainly doesn't feel as solid as a Ruger MK series pistol, but it is far from airsoft feel like the Chiappa 1911-22. It feels like a real gun in my hand and more importantly feels like a full size 45 ACP 1911 in my hand. Not only that, but it has the most robust magazines of any 22 pistol I have ever encountered including the Ruger MK series pistols.
That said, I probably wouldn't own it if it wasn't such a good suppressor host, but then again, I probably wouldn't own any 22 hand guns other than a double action smith model 34 and an old Ruger single six since honestly I just didn't really shoot 22 very much before I got into suppressors........and to be honest I still don't shoot it that much.
I had a sweet Ruger MK III host complete with the Burris Fast Fire III and the custom holster, it was the bomb digaddy dank. That was until the first time I shot it suppressed. It was a loud host that was a pain in the ass to clean. I just couldn't justify having a bunch of money tied up in a loud ass host that was a pain in the ass to clean, especially since I only shot it to show people how quiet suppressors can be.....which again it failed miserably at.
I keep the GSG 1911-22 because it is super quiet and when I shoot it generally the reason I am shooting it is to show someone new to suppressors how quiet a suppressed handgun can be.
