44AMP - bottom magazine release on that BDA?
Yes. Heel type mag catch. The trigger guard "hook" never bothered me, I did try to use it for a little while, but it didn't feel right, so I stopped, and now I just don't even notice it.
The mag release however did bug me for a long time. I did play the run dodge and shoot games for a while with the BDA, it was the only pistol I had then. The European style heel clip mag catch did make me slower than people using a pushbutton type.
Over time, however my resentment diminished, as I realized that #1, in any realistic real work situation I was likely to be in the very, very slight time difference in reloading speed wasn't likely to make a crucial difference.
And, I took up other games, such as looking at what might be valuable/useful with the impending collapse of society...(and just because we've avoided it for the last 40 years doesn't mean we ALWAYS will,
)….and I noticed a couple things...
first, the heel type release is about impossible to ACCIDENTLY release the magazine. Colt/Luger style buttons (which I do love, and prefer) can be bumped and under the right conditions, dump your magazine, or worse, just unlatch it enough to fail to feed...and extended mag buttons, used for that extra fraction of a second speed on race guns, are notorious for getting bumped at the wrong time.
The other thing that turned me off to the "speed games" was the required tactical reload. Looking at it from a (slightly) more real world perspective, and knowing that you will "fight like you train", it occurred to me that, if you were a single individual, without backup from others, or a support organization, dumping your mag, and 2-3 (or more) rounds to the ground might not be such a good idea.
They would say, "well speed helps you win and after you win you can go back and pick up your mags... " which is true in a game, but might not be in real life. And I'm using a gun with uncommon magazines, so tossing them means pretty quick I'm down to one mag, with no reliable source of resupply in bad times. Not a good idea, I thought. Works if you're carrying a dozen Colt mags, they're common and relatively easy to get more, but if you're using something else, then not so much.
the point being that I discovered that I was still a little faster reloading with a heel clip gun than a DA revolver and since I used those too, I didn't think I was going to die, die, die, due to being 1.37 seconds slower than the guy with the 1911. And I had my empty, or partially empty mags in a bag or a pocket to be reused when time permitted.
Fortunately, the real world has not, to date, ever challenged me to prove my opinion on this, and isn't likely to in the time I have left, so I'm not very concerned about it anymore...
Just my opinion, and I do prefer the "American" over the "European" standard, but have decided a heel clip is not a deal breaker for me.
FYI, "modern" SIG P220 mags (for the American button release) DO work in the BDA with the heel clip, IF they don't have a "bumper pad" on the bottom.
