Ordered an EGW Firing Pin stop from Shooter's Connection to use in a new .40 build. When ordered, there wasn't any toggle for caliber choice. Received the part and it says Series 70 .45 caliber on the packaging.
I looked on the EGW website and it looks like they have part number 1037, for 9/38, .40, and 1036 for .45 cal. Shooter's Connection only stocks one part number 1036 (45 cal).
Will the .45 caliber work in a .40? The stops pictured on the site look different. I just hate that I'll have to wait another week and spend more $ on shipping for one small part if it won't.
