Not to resurrect a zombie thread, but this one isn't THAT old...lol. However, this thread provides an interesting perspective since about 4 months after the last post, Ruger DID announce the come back of the 3" SP101! They made a few slight changes, opting for much nicer looking wooden grip inserts (instead of those fugly black plastic inserts) and a fixed notch rear sight, as opposed to the adjustable sight on the first production model.
I think the choice of rear sight is an indicator that it's aimed towards the carry market and it fills the nitch between the very small 327 LCR or LCRx and the trail/kit gun market for the 4" model with adjustable sights.
I personally think that magnum loads such as the 327 and 357 are wasted in a 2" barrel...just not quite enough tube to let most of the powder burn and get the projectile up to a decent velocity. 3" barrels seem to hit that sweet spot where there's enough velocity to justify a magnum load. I hope this one stays on the market for awhile.
The fact that Ruger just announced that they are also going to produce the LCRx in 327 shows that they are committed to the cartridge and see sales potential. Maybe the 327 was just slow to catch on. Ruger brought the first ones out and then Taurus and Charter followed suit, but then everyone just suddenly dropped the 327 models, only Ruger keeping at least one in the line.
With Henry now producing a 327 lever gun and 2 new Ruger wheelguns, maybe this second round will vault the cartridge into the public consciousness. A few full page ads touting the advantages of the 327 round over the 357 in small frame revolvers for carry and self-defense (extra round, lower recoil, slightly better penetration) would go a long way just to make folks aware of the round. It could be "the wheelgun cartridge for the 21st century", or something. I also always thought it would be interesting to see the ammo manufacturers selling the merits of the cartridge as opposed to the guns selling the round. Anyway, I'm crossing my fingers that the "new wave" of 327 offerings will breathe some new life into one of my favorite calibers.
