It happened to be a SIG 365 (failure)

Good example of stuff to watch out for when you can...

ESPECIALLY with your CCW or bear-defense guns...

It's why you carry a backup.

They break. A lot of rounds before they break but they do.

I’ve broken trigger springs in a Colt SAA.

I’ve broken transfer bars in Ruger Blackhawks.

I’ve even broken a hammer hook in a Ruger Redhawk.


I keep spares of each.

As I have stated before, my Dad put over 300,000 rounds through his L Frame .357 S&W over the years. It was repaired more than a few times. Amazing how much it was shot between those times. My brother has it and it's still a shooter!

It seems to me that the more compact that many pistols have become, the more fragile their internals.

Several years ago I ordered a new S&W Shield and before firing it checked the action and the trigger pull. After 4 or 5 times of dry firing it a little shiny piece fell out of the gun and it became inoperable. I took it apart and the sear had broken in two. Not at all confidence-inspiring. I returned it to Smith, got it back a week or two later and it seems to be all right. Actually I rarely shoot semi-autos so I haven't put enough rounds through it to have confidence in its reliability.

I looked it up on line and found that this issue wasn't all that uncommon.

I wore out a Department issued 686 years ago.

Sent it back to S&W and it returned good as new.

Department issued ammo in unlimited amounts is easy to abuse

Everything mechanical is subject to breaking or wearing out with enough use or miss-use. I wore a S&W 66 out, but it was used when I got it then I put a ton of hot loads thorough it. I also had a 45 Colt Blackhawk shoot loose, but it was also purchased used then feed a steady diet of hot handloads.

Good advice on carrying a backup, or at a minimum having one nearby.

I won't carry a firearm for CCW until I've fired 1,000 rounds of ammo through it without a failure.
For semiautos it has to be 'defense' ammo - not just FMJ practice stuff. (That got REAL expensive when I 'verified' my 45 ACP Para Ordnance - and towards the last 900-plus rounds, I kept thinking what if I've spent all this money and then it starts jamming, but it sailed through 1,000 rounds of Golden Sabre JFP so now I trust it.)

So true though that even revolvers can 'jam' and some of the failures can actually lock up the gun badly enough it can't be fixed without going to the bench.

"Staying away from trouble and bad situations" is the BEST thing to do of course, but sometimes trouble comes to you you can't avoid, and some of us (not me) have jobs where we have to go confront trouble, even other-people's trouble, so I think for them carrying two firearms at all times would make a lot of sense.
