After much Internet searching, finagling, and many acquisitions, I finally have my ultimate Franken-Glock 29/30 SF just about complete. With this, I can shoot .22 LR (Advantage Arms conversion kit with standard-length and extended barrels), 9mm (EFK Fire Dragon extended conversion barrels), .357 SIG (Lone Wolf extended, ported conversion barrel), .40 S&W (KKM Precision standard-length conversion barrel), 9x25 Dillon (Lone Wolf extended, ported conversion barrel), 10mm (KKM extended barrel for cast lead rounds and extended, compensated barrel for barn-burner loadings), as well as .400 Cor-Bon (Lone Wolf standard-length conversion barrel) and .45 ACP/.45 Super/.460 Rowland® (multi-caliber capable .460 Rowland conversion kit). I run these various barrel conversions with 15-, 17-, and 21-pound tungsten recoil spring guide rod assemblies from Glock Store, or a LaserMax 17-pound guide rod red laser, along with a Crimson Trace LightGuard modified to fit on a 29/30SF frame.
The only caliber conversion that I have not been able to track down, and I am still waiting to hear back from a few places, is a .40 Super barrel conversion for the G30 slide. Even though I have seen several instances on the Internet, including videos, where people have that very conversion barrel in various configurations, it seems that no one makes it anymore. I've already tried KKM and Lone Wolf, who stopped making it a few years ago and don't seem to be inclined to make it again. EFK Fire Dragon used to, and I have talked to the woman who is in charge of that to see if they either have a back-stock one sitting around gathering dust, or if they can custom make me one the way they did with my 9mm conversion barrels for the G29SF, so there is hope.
I'll be disappointed if I can't find one, but I suppose I could live without the .40 Super, since I do have every other possible caliber to shoot out of it if I so desire. Using .45 and 9mm to practice, not to mention .22 LR, definitely saves me money on range ammunition, but having numerous caliber options for specific purposes makes this a worthwhile project. Plus, I am going to set up the 30SF frame and a spare slide to use a reset trigger and laser trainer bullet for all the dry fire practice I could need, so even if I can't get to the range or the ammo stock is running low, I can still keep my muscle memory and training from getting rusty.
I give you the. . .
