I’m a “suppress all the things” fan.
For pistol hosts, I like the VQ variants of Ruger MK series uppers, with stock or chopped Ruger uppers as a close second.
Keltec P17 is surprisingly good and inexpensive AF.
I had poor accuracy with a couple of cans on an early Taurus TX22, but will likely try a compact at some point.
Glock G44 has been boringly reliable.
Sig P322… I really want to like it but the feeding reliability with those 20 round mags just isn’t in the same league with the previously listed rimfires.
