Had my trusty Model 27 out today and got about 10 FTF out of 100 rounds. NEver had this happen before. The only thi g I can think of is the ammo. Was using 158 gr LSWC from Magtech. Primer strikes looked good. Deep and centered. All of the rounds except 1 eventually fired, but some required as many as 4 tries. I'm not the original owner (it's a Model 27 no dash) but not aware of any trigger or spring work. The screw on the front strap is tight. During this same trip I fired some Blazer 357 with no issues. I found some info on google that suggests the primers are harder than normal with Magtech 38 special. Ideas or comments?
