The pinned barrel was the answer to problem with barrel coming loose.

 

22 Magnum runs at exactly the same chamber pressure (24,000 PSI) as 22 LR. It's just that there is more of it. I have a Zamak framed Frontier Scout 22 Mag only and while it has been carried more than shot, it has no issues other than the stamped steel "shock absorber" locking bolt, which reduces wear on the slot in the frame. But that is related more to the vigor with which the gun is cocked than it does the caliber.

 

That p.s.i. stat blew me away. Thank you for that tidbit. Kind of curious about the comparative muzzle velocity between .22Lr and .22 Mag being launched out of a barrel just shy of 5 inches. Will have to crawl down that bunny hole.

BTW, thank you for the reply, it's very appreciated.

 

Where Zamak loses its luster is in finish durability - in the wrong holster, it can wear 'just' like any of the lightweight receivers out there - refinishing doesn't happen like a re-blue - it's essentially paint.

When these show undue wear, the fix is 'Cerakote' or plating.

Get a good quality holster and wipe off grime and grit and it'll be just fine.

 

Would a soft non-leather holster be preferable, as opposed to leather?

 

'Personally' - I use leather.

Properly-fitted leather from one of the better makers will fit well and look good with minimal care.

The problem is that you're going to need to look at ebay for something from Bianchi or Safariland - your little Colt hasn't been made in awhile, and that's where those went.
