In hindsight, I would have spent the extra $150 and gotten a SP101. Having the revolver jam up after 26 rounds because they extractor rod backed out is not what I consider acceptable for a CCW. I wouldn't be as hesitant but just looking at the condition of the threads on my brand new revolver did not fill me with confidence. The overall construction is nice and it is easy to take apart. The rebate on the M85s right now make them pretty hard to pass up. I just like being able to have one gun shoot 2 different cartridges. That's my $0.02.
I had a SP101 for a while. It was my ex SIL's and he'd gotten deployed to another tour of Afghanistan and was going to pawn it. I told him I'd give him 250 for it and sell it back to him if he wanted when he got home. To my disappointment a year later, he wanted it back.

It was a nice revolver, but HEAVY. It was nearly as heavy as my 3" M66 Taurus and the 66 hides just as easy as any 3" SP101 (except the one I had was a 2.25") and carries just as easy and the 66 is a 6 shooter. It's also a might more accurate than the SP101 was, so I really didn't miss the SP101 THAT bad. About the only thing I preferred the SP101 for is the Hogue grip I had on it was a round butt profile and the Hogue I have on the 66 is a square butt style, a little longer. Not a problem especially now that Texas has open carry, so any noticeable printing is no big deal.
THEN, I ended up buying my 605 Poly, 2", round butt profile, and only 19 ounces. I carry that thing everywhere, especially in summer months under a T shirt. It's a strong design, reliable, well timed, accurate, and it is un-noticable during carry. I carry it on my belt. I could carry it in a pocket with the short grip, but that's where my 85SSUL rides.
Nothing wrong with the SP101, just a might heavy for a carry gun. If I'm going to carry that heavy, I'll just up it a few more ounces and carry my 3" Taurus 66. It's about 34 ounces and a SP101 3" is 28 ounces. A steel 605 is 4 or 5 ounces lighter than the SP101.
