GSG 1911 .22lr
I got mine last August. I admit at first I didn't immediately care for the "feel" as it is noticibly 'lighter' than a standard 1911A1 in .45ACP however that said I forged on and actually took it out & shot it.
Once I had the sights adjusted to the ammo I was using [mostly econo American Eagle 40 gr solid hi-vel] that is to say, with the highest front site that comes with it installed and the rear site adjusted for windage it shoots to the point of aim. Very accurate for what it is. I can chase golf balls around the back of the 25 yard range where I have shot it most. Inside 15 yards paper targets resemble ragged holes when the mags are empty.
I haven't "modified" mine beyond changing the too nicely checkered double diamond hardwood stocks for a set of soft Hogue grips panels and adjusting the sites to shoot to the point of aim. I have ~ 2K rounds thu mine without a hitch. Mostly, the econo American Eagle hi-vel but also Win Wildcat, Win Super X, Rem Thunderbolt, Federal Champion & some old Dominion hi-vel solids. It shoots like a champ. I have been very happy with mine.
And whats the deal with the take down screw on the frame? is that really nessesary?
On the GSG barrel.... on the question posed as to why the extra screw holding the barrel.... On the GSG the barrel is fixed at the breech end, not like the swinging link set-up on a traditional 1911/1911A1 that is held to the frame with the slide stop, the GSG barrel is secured to the frame with the extra screw with the allen head in the area of the slide stop. You will notice the barrel bushing is not "fit" to the muzzle end of the barrel like a traditional 1911/1911A1 either. The barrel bushing on the GSG is more 'cosmetic' & serves more to hold the recoil spring plug and assembly into the slide, than contributing to it's accuracy, like a "fitted barrel & bushing" in a traditional 1911/1911A1.
In ~ 30 years of owing many, many different 1911's including a number of Colt .22 conversion units, of which I still own one, set up on a Springfield Armory GI 1911A1 frame, I will say I think the GSG 1911 .22lr is good value for the money. I also own the following other dedicated .22 lr pistols at this time:
Ruger MkII 5.5" bull barrel
Ruger 22/45 MkIII 4.5" slab side barrel
Beretta 71
At this point my GSG 1911 .22lr is my favourite.
On a side note, I also discovered that the $30 GSG .22lr magazines work perfectly with my Colt .22 conversion unit....
