Ever since I got to shoot a suppressed GSG1911-22 in Nevada, I wanted to have on on hand. Rimfire trainer guns were extremely useful then and they have become even more useful since the price of ammunition gone up so much.
GSG 1911-22 has a good trigger and accuracy, little kick. It’s lighter than the standard 1911s but matches them in size, so the same holsters fit. Too large for kids, it’s just right for teenagers and women with small hands.
Chiappa mfour-22 on a polymer Omni receiver worked out well — it’s as light as Cav Arms lowers and as adjustable as the standard M4. Surprisingly good trigger, better than most milspec lowers. Accuracy with 1-4x Primary Arms scope was excellent. Reliability was also very good. Included 28rd magazine was too long for bench shooting, so I mostly shot it with BDM 50rd drum and 25rd box magazines. Light weight and adjustable stock make it very suitable for kids.
