I shoot 38SC Open, load 10.2 gr AA7, Hornady 125 HAP, CCI SPP, Star Line, approx. 1385fps. My personal experience, I didn't see a big difference between SPP or SRP, but if you start about 9 gr, should be a good starting point. I know a lot of folks use SRP, I just don't see the advantages, unless it's all you have.

Try cleaning a little more often, I don,t mean right after shooting, but I've waited two days after a shoot, and have no problems. Worse case, maybe some Hoppes'?

Have had two pistols done with APW, Bob and crew are great to work with, price is good also.

I put a piece of masking tape on the back of the racker, ensure both the screw and threads in the racker are clean, and a drop of blue locktite has worked for me for a long time.

I have use both SPP and SRP from CCI, honestly, I can't tell the difference? Have not tried the magnum primers, see no need. I haven't had any issues with either backing out, or not igniting. I shoot Starline 38 SC SSP as a regular load.

I'm a go on the Rugged Gear cart. I got it for Three gun 6 years ago, maybe longer, but use it for USPSA only no. I have the tubeless wheels, never a flat! Have had three shooters bags on it, the cart doesn't care. It is showing it's age now, but still working. I've used it all over Area 1, haven't seen any big rocks, but lots of sand, mud, and snow.

Well, I get 28 rounds in the mag, ran it this afternoon, no issues. Think I like the MG WIT 38-LF mag I got from Cotes, once I got done cutting, trimming, filing, and sanding. Oh, I forgot milling the TF ext base pad. Switched to MBX springs and follower. Cheaper, but the time I have into it, think the MBX is the way to go. Also got an e-mail from MBX, they said maybe in 2 to 3 months they'll be back in action on Caspian/Tangfo mags, getting the tooling fixed.

I would say that it depends on what scope you are mounting. I have a double side with a slideride and a single side with an RTS2. The size and weight difference may lend the slideride better suited to a double sided mount? I've seen a lot of folks using a single sided tho. I think the obvious advantage to the single side mount is I don't need to remove the racker to take the slide off. I myself have not had the issue of cases bouncing off the double side/slideride setup and going back into the ejection port. I shoot 38SC, so I can't speak for 9mm. I'm in the process of breaking in a new pistol with a single side/RTS2 setup, I do like that the scope sits lower to the bore. I'm having an issue with the shells getting caught between the slide and the scope mount, but that should work out as the pistol breaks in and the ejector gets tuned better. Because of the scope being closer to the bore, and not having to remove the racker to break the pistol down, I'm probably going to change the other pistol to the single side mount, but I'm not in a hurry.

MBX

The threads are great info, will give this some serious thought. I ordered a new Mec-Gar mag, will try with the TF basepad I already worked. The two mags I have, I'm pretty sure came from Caspian, are only marked 38 SA, they may be the same.

The catch does protrude into the mag body, does also on MBX mag, but the shape of the MBX mag does not allow the catch to come in contact with the bullets. How much did you have to squeeze the mags, loose any round count?

WhiteDingo and Dana4147, I'm having an issue with the Tangfo mags, while shooting, I can fell and see the mag release button move? I believe the mag release is coming into contact with the bullets while moving up the mag as the rounds are shot? Also, how did you squeeze the mag?

Good info, I'm holding off on squeezing my mag, I worry on how it will change dimensions and possibly cause other issue. As far as MBX mags, everyone I have bought for a couple of different formats, works right out of the package. I have had to send WRONG mags back, but once the error was corrected, no mag failures. I believe he is busy with his PCC stuff, and there isn't a big demand for the Caspian product to warrant MBXs' time.

My Caspian with a Caspian extractor will run 38S and SC without issues. I have never tried 9mm? Seems to me, that the shorter case on a 9mm would not headspace correctly?

I tried another follower, was looking thru my stash and found some STI 40 cal followers. Tried it this morning and it seems to work, only time will tell.

Well, finally got to the range to try out my mag with the TF basepad. Took a little time to machine out the back of the basepad, but I can get 28 rounds of 38SC. The feeding is hit or miss, sometimes all 28 will feed, other times 10 or so, and the bullet nose dives into the mag. I am going to try a longer follower, ordered the Grams spring and follower, think is for 9mm. I am also working with the feed lips and opening the back of the mag where the slide strips the next round. Seems the rounds stack more horizontally than the MBX, they have an upward angle.

Great info, should have the TF 170 base pad this weekend. Will keep you updated.

Thank you both for responding. I learned that there are sperate 9 and 38s mags, I just figured they would be the same. I ordered a TF 170 mag extension, have what I believe to be a Mec-Gar 38s mag? has 38 S A stamped on the side, will give this a try. I really like MBX, but can't get them right now, but if this works, way cheaper. I also got a Grams spring/follower from TF, should be in this week, will let you know how all works.

Which follower spring combo?

WhiteDingo, do you think this combination would work for 38SC? I load to 1.230" , .06" difference.

Thankx for the responses, I have been using MBX, really like them, but as we all know, they haven't made them for a while. My guess is MBX has put all their time and effort into PCC? I called to ask, and was told something about a move to a new building? Said they were taking requests from people and Caspian mags, probably waiting until the numbers get big enough to warrant running the machinery. Was hoping the Tangfo/Witnees folks were running the bigsticks and where they where getting them?

This is probably been asked before, but frustrated searching! I'm a Caspian shooter looking for 170mm length mags. I know Tanfoglio makes a large frame open guns, and am wondering where you are getting 170mm mags?

I've tried both, stuck with AA7, easier to find at the time. Shooters World is very similar to AA7, takes 0.1 grain more to achieve same PF. I'm not really sure that Shooters World is cleaner, but I always clean my pistol, so never had a problem. Oh, I shoot 38 SC.

I use blue Loctite on the screw and a small strip of tape in the dove tail. Have found that after removing/installing for cleaning, the fit between the racker and dovetail loosen a bit, the tape tightens it up. I now only install the racker for competition.
