Went to the range this morning. I went through 100 rounds of CCI Mini-Mags without issue. I switched to Winchester 555 round bulk pack 36gr plated hollow points, and had no issues. I estimate I fired around 350 rounds of .22lr total.
My sights are dead-on nuts POA/POI from the factory, no adjustments needed. Trigger feel on the M&P 22 simulated the trigger feel on the M&P 9 as close as it can ever get.
I can say that in my hands, the M&P 22 is not as inherently accurate as my Ruger 22/45RP. The M&P 22 is no slouch: I can keep 2" diameter groups at 30ft. This is perfectly fine for what I need it to do.
I picked up the M&P 22 for an inexpensive training analog for the M&P 9. The M&P 22 fills that role perfectly.
I cut about 3" squares of cardboard, stick on a 2" diameter dot, and put them out between 21ft. - 30ft.
This is last week's M&P9 target, before I acquired the M&P 22.
This is this week's M&P 9 target:
I'm beginning to get tighter groups! I still need more practice.
The M&P 22 definitely helps me get better quality practice in with my M&P 9. I'm able to warm up & work out the kinks on the M&P 22. When I grab the M&P 9, I'm ready to go.
Before the M&P 22, I'd burn 300 - 350 rounds of 9mm through the M&P 9. This last range session, 100 rounds of 9mm.
