They're Very Loosely based on the JBM and are, IMO, a real piece of junk.I tend to carry a Bauer .25 auto (based on JMB baby browning) in which case since the safety on this striker fired pistol is not very positive I tend to carry it without a round in the chamber.
Personally, I've started Carrying a Military 1911A1 when I was 19 and have seldom Carried anything smaller, unless it was a BUG. But to each his own. With Luck you'll never NEED anything. Me, I've not been that lucky.
