    Going to build another 1911. Have a Baer frame. I have 5 .45's and thought I would do a different caliber. Right now I'm stuck between building a 9mm upper with .38 Super barrel that I could swap back and forth, or do a 10mm with a .40 barrel. I like the idea of cheap and plentiful ammo, and the history of the Super, but the 10mm packs a lot more punch. Would also be nice to have a 9mm 1911 for the womenfolk and younguns to shoot. :D Really could care less about the .40, but I do have a couple boxes of ammo already to shoot through it. I reload for 9mm already, so no concerns there. I also can make a 9mm 1911 run without a ramped barrel. Slide and barrel will come from Remsport, probably.

    I voted 10mm because i am a 10mm junkie. It sounds like the 9mm would be best for you, though, and way more economical.

    What do you want to use the gun for? If range, I would go with the first option

    To shoot. :D Could be kept in the truck, could be range gun. If I went 10mm, I could use it for deer hunting.

    I've got 1911's in 9mm, 38 Super and .45ACP, so I eventually want one in 10mm. :nod:

    The penetration and reach of the 10 for 4 legged encounters. Stupid question. Doesn't the 9 and 10 have the same case rim diameter? What would be involved in setting up for both or is it even possible?

    How much different kinds of ammo do you wanna keep track of?

    No. The 9mm has a case rim diameter of .394" and the 10mm is .425". While it may seem like not that big of a difference it is very big. The 10mm really should use the .40cal slide because of this. Now, has it been done before? Sure, a few manufacturers have tried to cut a corner and use the .40cal slide for both...and had some problems.

    I was too lazy to look it up myself. LOL. Thanks Joe. Don't know why that came to mind, or what's left of my mind. Probably LGS blather concerning one of the guilty corner cutters.

    Had I read your first post before voting I would have suggested the 9mm instead of .45. I see that you already have a couple of .45's currently. I've read several posts lately where members went with a 9mm 1911 as a range pistol. I've not given much thoughts about a 9mm 1911. I have 9's in other pistols so thats covered. Additionally, I reload the 9mm. I kinda feel like a 1911 is traditionally a .45, and kinda stuck on that philosophy. I need to purchase all the necessary accessories to reload for the .45, I just have a small stockpile of the .45 I purchased in anticipation of my first 1911 purchase and need to use that up. I'm sure the 9mm 1911 is a popular idea, especially if it's for economical reasons or just volume shooting pleasure. I do have a 9mm emp, though it is classified a 1911 compact, I feel more like I have a 1911 in hand when I have a commander or govt size pistol in my hand. 9mm is a great round to shoot, and you can really tailor a nice reload to suit your purposes, especially a good sd round. In the future I'd like to shoot a 9mm 1911 to see what people are saying about them applies. Maybe as I age (more) I'd be leaning more toward the 9. Today the 1911 is a .45 to me!

    For me, it was just the economics of it all. Since I dont reload, I'm very sensitive to the price of ammo. When my major source of .45 started increasing prices, I really started giving some thought to a 9mm 1911. I had a chance to buy a Springfield Loaded in 9 back in February, but at the time, I hadnt really convienced mysels on the idea yet. I heard some others talking about the PM9 from Dan Wesson, what a great gun they were, and how scarce they were. Well I did find a NIB 2011 PM9 and went ahead and bought it.

    The thing I like is that it weighs 38oz, the same as my Valor. For a range gun, it gives me a chance to do everything I do with my other guns at a lesser cost, and for me, that became very important. I dont know if I would have more than one 9mm 1911, but I'm happy to have the one I own.

    I voted for 9mm. Cheaper, lower recoil, and you already reload for it. I've really seen the 9mm 1911s picking up speed in the last ten years or so. They seem a lot more popular than they used to be. :thumb:
