Tim- I can't see why you'd want parts for that gun right now. Don't go replacing anything. Shoot it the way it is.
of course i'm partial to the CMORE, as i've been shooting it almost faithfully for 4 yrs (with the exception of one season where it broke, but its not really the sights fault, i had some custom work done to it, the on off switch was removed and changed to an entirely different style, still not available, and for some reason, the knob blew off, for the past 3 yrs, it hasnt had a problem)
The Holo Sight base cracked, and i've also seen a number of them just stop working due to damage inside from the heavy recoil of the 38 supers.
Mags- Craig sells them. I wouldnt get a 170 tube. But thats only because i do have one of his from about 5 yrs ago when i was shooting a caspian, and it never fed reliably. I imagine a lot of people have caspians out there they aren't using anymore becuase they switched to higher cap STI/SVI or Para's. stick a want ad on the memebrs page.
Loads- i bounce from 124-125 to 115 grain bullets, and use Vecatan SP2. I usually use the Zero 124 grn bullets, as they seem to be the best for the price.
I'm loading 10.3 grains of the SP2, and pushing out 176pf according to last weeks chrono stage.
more than necessary sure, but i dont feel like chronoing loads all day.
I can probably drop to 9.9 and still be over 165.
SP2 is a lot cheaper than the Vhita Vhouri, is it dirtier? yeah, but i still only clean my gun once a yr, and you know it works from my results.
Grips- you dont much need em. If you need more surface to hold onto, just get the griptape.
holster, i'm probably the only one using the Aluminator anymore. CR speed holster isn't all that expensive compared to some of the other ones.
