the 22/45 fixes a lot of the issues of the standard models.
on mine i fixed all but one issue of the remainder.
i removed the magazine safety which allowed the mags to drop free. and i removed the loaded chamber indicator which let it run for several thousands of rounds without cleaning or lube. with the indicator functional crud would collect under it until it would fail to feed in less that 500 rounds.
the one issue i havent fixed (cant yet) is the bolt release doesnt release automatically by pulling the bolt rearward.
the issue i hate about the standard is heel mag release and grip angle.
