Glock 30 Conversion - 10mm or 45 super?

Jacket67 · January 24, 2020, 11:35 PM

Ive been thinking about this a lot recently and wondered what others might suggest. I love 45acp for self defense from 2 legged threats, but it's lesser penetration has me wary of carrying 45acp for woods protection with black bears in the area. So, I've been considering getting a conversion kit in either 10mm or 45 super when I pick up a Glock 30. Which of the two would you suggest? I like the thought of being able to shoot regular 45acp in the super barrel and just swapping out the recoil spring when using the heavier loads, but 10mm is always been an interesting caliber to me. How hard is it to find 45 super ammo vs 10mm?

Thanks in advance.

On one hand, a .45 Super conversion is likely easier and less expensive. (Maybe a heavier recoil spring and that's it?)

On the other hand, 10mm Auto is more widely available and less expensive.

If it were me, I would look into a .45 Super conversion first, just to see what it requires. If it's as easy/inexpensive as buying/installing heavier springs, then go for it. Otherwise, 10mm.

Here's some info on a glock 30. It says you can use a factory 29 barrel in your 30 among other conversions.

45 Super for the win!

It's like ever since I made a thread months ago about 10m vs .45 Super vs .460 Rowland everyone is talking about .45 Super. It's still a hard choice for me, but I think as long as .45 Super remains scarce like how 10mm was 7+ years ago, unless one is planning to reload their own .45 Super, get 10mm.

If you aren't reloading, the price difference of decent S&B or PMC 10mm and Underwood or Buffalo Bore is extreme.

Just buy a G29 in 10mm. The better 10mm loads beat 45 Super and you can always use 40 S&W level loads (that beat 45 ACP) for 2 legged predators. 10mm is readily available and ammo prices are exactly the same as 40 S&W ammo. Cheaper than 45ACP. In fact Glocks in 10mm shoot standard 40S&W ammo just fine through their 10mm pistols with no modifications.

If you already have a 45 and don't want to add another caliber then just use some of the heavy for caliber hardcast 45 ACP loads available from DoubleTap, Underwood, and Buffalo Bore. No reason to pay for a conversion. Those loads in 45, 9mm, 40 S&W, and 10mm have proven effective on big game. All of them have successfully been used to stop bear attacks and hunters have used 10mm on game as large as cape buffalo.

That ammo isn't cheap, but you won't shoot a lot of it. You can use standard loads most of the time. Shoot a box or 2 to ensure your gun will shoot it then a box will likely last for years.

FYI: For anyone seeking .45 Super, .45 SMC is the exact same thing, just using a proprietary name.

If i were to shoot much .45 super from my glock, I’d probably want a fully supported barrel.

I’m one of those jerks that shoots .40 in my 10mm guns without a conversion barrel though.

I’d go .45 acp for the base model, and go from there.

Ruger45LC · January 27, 2020, 11:54 AM

A few thoughts based on my experiences, one the 45 Super is great but really unless you handload, what you buy isn't that hot. As long as you're okay with buying online, ammo availability isn't an issue. The positive aspect of the .45 Super is that it pokes a bigger hole and really all you need is a better supported barrel, definitely don't use the stock Glock .45 barrel for .45 Super, the reason is because Glock 45's have abysmal chamber support because they're only designed for the relatively low pressure .45 ACP, shooting .45 Super through one would be borderline dangerous. Personally I think the Glock 21 Gen4 handles it better, the G30 is slightly more packable, but it's not like the G21 is hard to carry.

Second, I don't think the 10mm conversions for Glock .45's are the most reliable in the world, so if you were leaning towards 10mm, just get a G29 or better yet a G20. Because you like the 45 already, I'd lean more towards just getting a good barrel (like a KKM) and get some .45 Super for when you're in the woods. Either way, get a Gen4 because the Gen4 recoil assembly is much better at handling potentially hotter charges than the Gen3.

G29, the G30's brother in 10mm looks like what you ought to buy from the get-go. They shoot well and are the subjective recoil is mild.

If you really want a G30 due to .45ACP goodness, maybe you ought to stick with .45ACP+P loads instead of .45Super. Penetration is a bit more for .45Super with 255gr hardcast FP, but not that much better.

Pistoler0 · January 28, 2020, 04:32 PM

45 Super only available online (you can also try DoubleTap 450 SMC, same thing) or hand load.

But regular 45 ACP much easier and cheaper to buy, and also when compared to 10mm. I don't think you can get 10mm ammo in bulk as cheaply as 45 acp. Last time I bought 1000 rounds of 45acp at surplusammo I paid 0.26 per round, that is including tax and shipping.

No need to change recoil springs back and forth, I don't think. At least on my Glock 21, the 24# recoil spring shoots both 230gr 45 ACP and 45 Super without a hickup.

I went the Super route. I only use Super sparingly, and do a lot of practice and competitions shooting with 45 ACP which is cheap and easy to find. I only load the Super when in the woods or hunting.

I kinda did that for my SR1911 CMD, but I hand load my own 45Super.

yep, that thread in glocktalk is legendary.

I signed up to glocktalk just to be able to reply in that thread, but my account has never been cleared for some reason and I cannot post, go figure.

But it is a wealth of knowledge.

Can't find .45 Super ammo at Walmart or Cabelas.
