Love my 10mm. I was introduced to 10mm when the chief of my agency made the Glock 20, 10mm, the issue weapon of the department immediately after the FBI endorsed it, before they wimped out. I was drafted to assist the armorer transition our agency 120+ sworn personel to the Glock and to 10mm. That said I have run through a few thousand rounds of 10mm. I like it.
After I retired I got away from shooting for a while, then after a few years really got to wanting another 1911. I was in my local gun store checking out the various 1911 .45acp in the display when I spotted a stainless steel model, with rubber grips and a red delta symbol on those grips. My mind was made up when I saw it was a 10mm, Delta Elite. It has been a most frequent carry gun ever since.
I got more and more into shooting again and not being a real Glock lover, wanting to add a gun to supplement my FN Browning HP, I stumbled across a Sig Sauer P226 Elite. It not only felt good, it looked really good. It still does when I pull it out. A while later I saw a similar Sig in the gun store. It was a Sig P220...That was an immediate sale, Elite version (stainless steel w/ rosewood grips). It too felt and looked great.
I put a few hundred rounds, mainly Federal and Seller Bellot ball through the p 220. It performed flawlessly. As someone said, it is not a discrete carry weapon, but I've carried all steel weapons all my career, so I didn't mind that.
The problem arose when I attempted to load heavier S&B 180 JHP into a magazine. It wouldn't work. 180 gr ball was no problem, but the JHP simply would not feed into the magazine. I had 5 magazines, all Sig Sauer manufacture. I tried other brands of ammo, including Sig Sauer 180gr JHP, none would feed into the magazine. The next step was to contact Sig Sauer direct. I spoke with a rep and explained the problem. He claimed to have never heard of such a problem, but was willing to set up me returning my pistol to Sig, along with the magazines for their engineers to check it. Before I did that I decided to do some more online checking. I found a board where this very same problem was being discussed, loading heavier JHPs into Sig P 220 magazines. The thread was several years old. I found that several had encountered the same problem. One gent had fallen for the return to Sig, where the pistol sat for 6 months with no response, until he finally demanded it back. It seems the tollerances in the magazine design are so tight that a heavier JHP (180 gr) is too nose wide to fit. The extra weight of the projectile has to so somewhere, so the bullet is fatterfarther towards the nose than the lighter loads. The lighter weight JHPs would feed all day long with no problems.
After all my research I was no longer happy with the weapon or with Sig Sauer. This old man does not like being lied to as the representative did. The simple truth from the rep might have been different. After the pandemic started to wind down and things were opening up, and dealers were getting desperate for guns to sell, I offered to sell my P220 back to Bud's. They asked how much I wanted and I quoted them what I had paid for it. There was no haggling, they sent me the shipping information immediately.
I still have and carry that Delta Elite. Should I decide I have to have another 10mm for some reason, Ruger and Springfield both make good 1911 style 10mm pistols.
