got myself a Taurus 327 federal Magnum, mainly for its ability to chamber multiple calibers which I find useful, but those who shoot the 327 federal or 32 h&r Magnum, how would you stack it against say 38 or 357 Magnum? or even mm as far as performance, accuracy, reliability for stopping a potential threat etc? I got a box of Hornady 80gr I believe xtp or ftx, whichever has the red polymer insert in the nose. and got a box of pmc bronze 32 acp as I've also seen it can run 32 acp in a pinch, but that's just more for plinking use.

who would or wouldn't trust their life to a 327 federal Magnum?

I think that it's a good performing caliber but is relegated to share a place in history with the .45 GAP, .357 SIG, .30 Super Carry, etc.

I bought a Ruger LCRx and an SP101 in .327 this year.  32 S&W ammo is very mild.  32 H&R is not bad either.

Only fired a few cylinders of real deal .327 and it is stout.

.327 brass was backordered at starline for a few months but I am set now.  I've been loading relatively light loads, 4 grains TG with a 78 grain LRN and 3 grins TG with a 98 grain WC.

Good accuracy overall.  Not sure I would carry it in favor of a .38 snubby or .380 auto, but possible.

I like oddball calibers (10mm revolvers, .41 mag), that's why I bought them.

Well another reason I got this thing too was to have something My lady can shoot, sh hasn't much experience shooting handguns and has wrist issues in her left wrist from a past injury and cant operate many slides on smi autos. sh is also recoil sensitive, so I figured this would be a good way to ladder her up from 32 acp and then up to 327 mag, and once sh is confident and comfortable with that then move onto others. but that's 4-5 calibers she can work through all on one platform, plus its something shee could carry as well regularly. i have been carrying it myself too and have found 327 federal and 32 hr mag ammo regularly.

I would not count on 32 acp for defense.there are reports of inconsistent headspace .  Try it at the range and see.

32 H&R should be fine for a recoil sensitive shooter.
