Both the M&P22 and the M&P22 Compact are hammer-fired guns, albeit internal hammers.
The SR22 would have held more interest for me, but the "up is off/down is on" safety is counter-intuitive, and unlike most (all?) other pistol safeties.
Ahh ok thanks.
On the SR22 safety, it works similarly to a Sig decocker (ie it decocks), so for me it's a reasonable equivalent. I do not use the safety on mine as a safety, not that I carry it outside of the range, but the trigger is heavy enough no need - just flip the safety on/off to decock if desired then holster.
