Using one of Rock Island Armory’s newish .22 TCM caliber 1911s, 22Plinkster gives the zippy little Armscor 40-grain jacketed hollow-point a shot at making it through some ballistic glass.
The TCM round (.22 Tuason Craig Micromagnum), with limited loadings, has found some fast love with early users and when you are talking about a round centerfire .22 that trucks at 1875 fps, you can see why.
But, will it penetrate bulletproof glass? Of course, nothing is really bullet “proof” but it may be resistant enough for the spicy import.
