Called them about my 20 year old recoil spring that broke, thinking might as well.
I never bothered to register my M1911A1 Standard.
Tricia asked for the serial number, my name, address, & phone number.
Said I'll get that recoil spring right out to you.
No big deal if it wasn't covered; it's a $2.99 part from Brownell's. Prolly will order a spare anyway; but, just wanted to give this example of quick, hassle-free warranty service.
