Glock 29 is my preffered gun, by a big margin. Outfitted with the Glock adjustable sights, G 20 mags with Glock mag extensions makes the grip length issue go away. Use a 180gr Speer Gold Dot HP and FMJs hand loaded fairly hot, runs about alot faster than a 40 in a similar barrel lenght. Had, and sold a 20, never carried it hunting, hiking or CCW, preferring the short light efficiency of the 29 to the 20. The weapon is far more accurate than most folks would believe. I still have alot of pistols, but this has become my go to, my biggest concern is the black bears with cubs I often encounter while hiking. There I mix the load FMJ, HP, FMJ, HP....
In the early days of the Bren 10 and the Delta Elite, the original loads were 200gr and very hot, giving the cartridge a reputation for heavy recoil. And it was hard on the Deltas. Hand loaded within reason, or as factory rounds now are, its an effective controllable defensive round, and the Glock 29 very adaptable to general carry.
The 10mm has a cult following, spread across the internet. You'll find alot of people going to Wolf barrels etc, and really loading the pistol to the old specs. Which is pretty much a 41Mag load. Been there, done that, in the early days of 10mm, hard on the pistol. Not a good idea to buy a used 10mm off the internet for that reason.
Some of the older FBI guys still carry the old Smith 10mm by choice. If it ever came down to a court case, that is use full information. I think it a good choice for ccw.
