That is a “D” mainspring for a Beretta Cougar. The internet says that it will fit into a Beretta PX4 Storm. Today we’re going to find out. This is one of the best things about my job, when I get to experiment with stuff like this. Real useful consumer testing!
Thatt same D spring (along with the little TW25B) will work wonders on a Beretta-92/96 as well.
Brownell’s sent you a “D-Bag”?
Been doing it since forever. Mac-10’s, 1911’s, Ruger 10-22’s, Revolvers, other Auto Firearms,Rifles. Did I leave anything out. Tools from Brownelles, made my own, bought a machine lathe for threading and other. Don’t do much of it anymore–No Time now.
