I mistakenly shot .45 GAP ammo in my Smith & Wesson M&P .45 ACP. Will this damage gun?

Question

I bought three different brands of ammo to try first time at range with this gun. I started with the Winchester (which was actually 45GAP, but which I didn't notice until later) and it jammed repeatedly on ejection so I switched to the other brands. I shot about 20 rounds total of the GAP. I then fired 50 rounds each of Blazer and Speer 45 ACP without any apparent problems. Could this mistake have caused any serious damage to the barrel / feed ramp or other parts of the pistol in some way -- -- should I have a gunsmith exam the pistol before firing it again?
