One Couger .357 build coming eventually

Post by AndyC » Wed Jun 27, 2018 6:07 pm

Snagged a brand-new 4" Colt Python barrel (new old stock from the Colt factory sold at auction); this will eventually go towards building a Couger (Colt barrel on a Ruger frame) which is something I've wanted for a few decades now.

Will the threads match, or will the barrel or frame have to be rethreaded?

I'm no expert on the specifics but my understanding is that the barrel threads have to be welded up, machined down and re-threaded.

Andy, I totally get the "just because I can" reason but is there some other reason for doing this?

Thanks

I am wondering if the value of that barrel will be much better as is. Pythons are commanding some pretty high prices these days and it looks to be going higher.

I suppose if one can put Chevy engines in Ford Body's, why not with guns?

Seen one today at a Pawn Shop that was about 80% at best for $1,500.00.

Sorta-kinda. I love the looks of the Python but I've never been impressed with the longevity of the Python mechanism (which really is a by-product of the precision of its lockup), whereas the Ruger frame is built like a bank-vault. Python barrels are known for their accuracy and combining a superb barrel with a strong action is something I want. Here's an example (with admittedly chunky grips):

Image

Further info on what gets done via Alex Hamilton of TenRing Precision:
The conversion includes rethreading the Python barrel, double ball yoke detent front lockup, milling out the Python barrel ejector rod slot, setting the gap, cutting the forcing cone to 11 degrees, freshing the crown and test fire for proper function.

Keeping it .357 Magnum, or going .357 Bain & Davis as per the write-up in Guns & Ammo magazine in the early 1970's?

I was expecting to see a Beretta Cougar 8357 in 357 Sig.

Regular .357 Mag - no interest in wildcats for this thing.

I'm just guessing here, but I wonder if the barrel could be sleeved with a sleeve that was threaded inside and out, then pinned into the frame.

I reckon I'm safer handing this over to a pro who's done this before.

Why? You don't trust an attorney playing amateur design engineer/gunsmith?

Thanks Charles for the laugh out loud humor!

None of us get enough of that.
