Can factory .40 S&W magazines be used instead of the .45 GAP magazines with your conversion follower?

.45GAP magazines will not work due to the feedlips being too wide to hold the .40S&W rounds. Factory .40S&W magazines can be used, however due to the way the .40 follower interacts with the slide stop, it may not lock back on the last round. This is why we include an follower with the kit. The kit works well with either a 9mm follower or a .45GAP follower. The kit also seems to run great on standard 9mm G17/18 magazines, you just can't fit as many rounds in them.
As for conversion to .357SIG, unless we see a substantial increase in demand, we will stay with .40S&W.
