I'd do it if I had a Glock. 8) I was able to just buy a barrel & mags. to convert my 10mm Witness to .40 S&W. for about the same price. to convert to .45acp, 9mm, etc... I would have to get a different slide too. almost as much $ as another pistol!
A couple years ago I ordered that barrel. Was on back order for over a year with them not able to give any idea of when they would be making them again. I gave up and sold my 30. I do have a G21 that i have the Storm Lake 10mm conversion barrel for. I found it used. Works with jacketed ammo real well. Like all of my Storm Lake barrels it is finicky with lead and coal.
I like 10mm and to a lesser extend .45 +P. But, I don't like Glocks. That said, if I did like Glocks I would not get an extra barrel to change the caliber of a pistol to another. As cheap as Glocks are I'd just as soon buy the second Glock in that other caliber. That solves two issues. First, you now would have a pistol that is chambered for and designed to handle the proper ammo. Secondly, if one of those two pistols goes down (parts breakage or some other problem like maybe you have to shoot someone and that pistol is taken by police for evidence), then you have a second one to take it's place.
You like Glocks or you don't, and no one needs a reason or justification for either way. I don't "like" them, but I have a lot of them. They just work. First time. Every time. Very few pistols can make that claim. Cost and versatility of the platform are added bonuses.
Price matters, to a lot of folks. There's about a $250-400 difference converting calibers vs. buying another Glock pistol. SL barrels are more costly than the comparable quality, IMO, when an LWD barrel is about $100. New Glock OEM barrels are about $150. I'm not saying LWD barrels are better (with the exception of the Alpha Wolf line), only that the level of quality is at least on par with more expensive alternatives. I've had SL barrels and was not impressed.
Shooting 10mm in any Glock .45ACP pistol (except G36) is a simple matter of adding a barrel, and on occasion, an extractor or RSA upgrade (LCI extractor required for reliable operation, and some should have an RSA upgrade). There's nothing complicated about it, and it works. Having another pistol, because one "might go down" applies to any firearm, regardless of caliber or use. One pistol or two, is only one pistol or two. Additional caliber(s) for one doesn't change that. It does, however, add versatility, one pistol or two. My summer carry pistol is a Glock .357 Sig, but not a .357 Sig. It's a G27 with a G33 barrel (Alpha Wolf). Glock 33's were out of stock at the time I was shopping for one, while G27's were aplenty. The only difference between the G27 and 33 is the barrel and markings (Glock .40SW mags work fine with .357S). The only functional difference between the Glock 20/21 and 29/30 is the barrel, slide mass, breach channel and possibly the extractor. Chambering 10mm (or .40SW) in a Glock .45 slide with LCI extractor is fine, but the indicator doesn't indicate (it remains flush, but functions normally, like a caliber-correct non-LCI extractor).
Spend the extra cash if you want, but unless an additional pistol was already in the plan, it doesn't make sense. In an ideal world, we'd all have (at least) one pistol of every brand, in every caliber, with an inexhaustible supply of ammo for each. I'm working on it, but alas, this world is far from ideal, and we settle for what we can have.
