Generally 40 Cal (40 S&W) Glocks and Sig Sauers can be made to shoot .357 Sig by simply replacing the barrel. This is so because the .357 Sig cartridge is nothing more than a necked down 40 caliber casing utilizing a 9mm bullet. Since the cartridge casings are of the same base diameter no magazine change is required. 357 Sig is an exceptional round offering better balistic coefficents than a 9mm at distance. It also lends itself to heavier bullet weights. From my experience 9mms don't really perform well with heavier bullet weights. This is where the .357 Sig shines. Being a bottle neck pistol cartridge, preformance is greatly enhanced. Other 40 cal pistols offer this capability as well. Hope this helps.

So, from reading this it sounds like I can do the 40S&W, 357 and 9mm conversion with a barrel change. If the 357 is a 9mm bullet in a .40 casing.

What about the Glock 30? I'd really like to find other caliber options for it as well. I'd like to know if I could switch it out for something like 10mm.
Or do I need to go with a gun that shoots 10mm then get a 45ACP and 45GAP barrel.

I want to make sure you are clear on this issue. You can swap out the 40 cal (40 Smith & Wesson) barrel with the .357 Sig barrel (Not to be confused with 357 magnum). You CANNOT swap the 40 cal or .357 Sig barrels to shoot 9mm. Case/rim diameters are NOT the same.

As far as your Glock 30 you CANNOT swap out barrels to shoot 10mm. As far as swapping barrels on your Glock 30 to shoot 45 GAP I have NOT heard that you can do that. 45 ACP cartridges utilize large pistol primers where as the 45 GAP uses small pistol primers.

OMG...why not just pick a caliber and stop f*cking with the ordinance in the first place......

Hey Saw

It'll be alright, it's a learning curve thing. BTW the correct term is ordnance, ordinance is a Law/Rule.;)

Having the additional barrel is a good option, if ammo is scarce and you do not reload. It gives you options and is easier/cheaper than multiple guns. But, the 357 sig is not very common and it might not help much. I liked the Desert Eagle that would do 357, 44 and 50 with just a few extra parts. All common rounds, except the 50, and provided numerous options if needed. But, I was not a fan of the DE itself, after owning it. Lots of FTE's on mine, but YMMV.

I would have to agree on the Desert Eagle. I have a very very low opinion of them. The make good hammers in a pinch. The IMI Baby Eagle is a great firearm being based on the CZ 75 series pistol.

Hey, I found this.

Let's see if I can post links.

LWD Barrel M/23 Conversion to 9mm Threaded 1/2 x 28 Black

Storm Lake Barrels also has a conversion kit.

http://www.stormlakebarrel.com/

I think that should work for what I want to do. .40S&W, 357 Sig, and the 9mm. One gun multiple options. If ammo runs out for one just switch the barrel and go go go.

Also, I found a few options.

For the Glock 30 I found a Caliber 45ACP->10mm Conversion it can also do 400 CorBon whatever that is. I wikipedia'd it. I'll have to think about the 400 CorBon.

I'm really excited that I found options that really will work for me.
