Chico, I've had the "Rimfire Target Conversion Kit" for a couple of years now and love it. It fits on my 4" and 5" 1911's and I've never had a problem with it. I like it so much that I've been toying with getting the "Rimfire Compact Conversion Kit" that fits 3" and 4" 1911's.
The issues to me have been long term reliability without cleaning or adding lube. Or having to have so much lube on it that it is unsightly or getting on my hands.
And the ability to run it like other 22s...1000 rounds or so without cleaning.
Less dependance on certain makes of ammo. I want it to run on everything...including the standard velocity cheap stuff.
Able run error free the way I shoot centerfire 1911s...in other words, some thumb pressure on the side of the slide from a high thumb grip should not sit it down.
Lighter hammer, lighter mainspring, relieving the frame rails to reduce contact with the slide grooves (thus reducing friction surfaces and giving places for powder reside to go ie. "sand cuts").
A recontoured mag well so that all mags seat easily. The Kimber mags suck in guns with mag wells including Kimbers mag well.
Install a steel insert into the slide notch so that locking back on last round with GSG mags does not peen the notch in the alloy slide.
