People have been churning out defect-free designs for many decades. It is surprising that a company with the engineering experience and pedigree of SIG Sauer would design something with this issue. It would be like if Airbus designed a pl…
Not that rare. Gen 1 and 2 Glocks had slam fires (that's right, "Safe Action" Glocks... the irony). The XDS had doubles or slam fires. I'm sure there were others, and now the P320.
