I'm heading to the range today to try out my first entry into the .22 semi-auto pistol field. (My poor arthritic hands needed some relief from CF loads). I looked at all the models mentioned, but chose the Ruger Mk IV 22/45 Lite. Reason being ease of maint, familiar grip and controls, a threaded barrel, and a Picattinny (sp) mount for the optic that I'm going to need since I'm half blind in my dominant eye. I can shoot well and fast with the other eye, but it will be nice to try it out and see what happens. Also attractive is the availability of trigger kits cuz I love a good trigger and hate squishy/gritty ones.
I also just finished replacing broken parts on my 1022 after the granddaughter used it. The extractor was so worn it fell out while she was shooting. Then the recoil spring guide rod went "SPROING" when I disassembled the rcvr to put the new extractor in. Had to order a new guide rod from RugerParts.com or some such and it took forever for them to ship it. sheesh. Gotta shoot it today and make sure the new parts work. I put the Volquartsen trigger kit in it long ago, and also have the nylon recoil bushing. With the heavy 7/8" replacement barrel, its a very nice shooter for squeaks or steel silhouette.
