This one is a used Mod 61-1 S&W 4 inch .38 Special. It was very lightly used. It had a Pachmyer decelorator grip on it that made trigger reach uncomfortable for me, and the Mrs. Came out to $320 with a Houge Mono Grip. Mrs. M&P likes it so much she thinks I should get one for myself.
This one cost me $325 has been a good gun. I had to do a little sanding on the grip to keep the texture on the grip from sanding my side when I carry it. Sig P250 9mm Sub Compact. The trigger is way heavier than my Glock 26 tough the Sig is slimmer, and holds 2 more rounds. It feels a little lighter as well. Mrs. M&P states she wants to carry it in place of her Bersa Thunder 9 mm Ultra Compact due to it being lighter, and slimmer. Recoil is a bit snappy though managable. I may get another in .45 ACP for me, though I have been eyeing an Colt New Agent, or one of its clones for a while.
