    1911 Vs 1911-1A What's the Difference?

    Hi everybody, I am in the market for some cheaper magazines for range plinking and have a question for you. Whats the difference between the 1911-1A and a 1911? I have a new TRP Operator that is a 1911-1A and can find lots of magazines for about 7$ for 1911's(7round). Will they work? Does the 1A just indicate the safety?
    Thanks in advance for your help

    They take the same magazines.

    Please keep in mind that the magazine is an integral part of the system. Buying cheap magazines for your pistol, is like owing an expensive car and ask which are the cheaper rethread tires you can put on it. Don't do it. Read the bad experiences of others with those cheap magazines. Buy the best magazine you can afford.

    John is right (of course!) unless you're talking about the deal on new magazines using Springfield's "loaded" coupon. Springfield uses a good quality produced magazine, and their deal with the coupon can't be beat.

    But if you're talking about some unknown brand of magazine for $7, then I'd stay away. I think a lot of us have been bitten by cheap magazines at some point. They're not worth the money.

    Also, as with my sign-on name, the firing pin stop was changed from the long radius to the tapered version that enabled the user to rack the slide with the hammer down much easier...

    To most, not an improvement, and changed recoil handling quite a bit. EGW sells a part that replicates the original Browning design and should be considered in any 1911...

    No sir, that was not a 1911/1911A1 change. The old .078" FPS was changed to the new 7/32" around serial number range 240000, or 1918. The 1911A1s have always had the "new" radius.

    I stand corrected -- your dates are correct, however, I wanted to note a major change to the original M1911...thanks for the heads-up
