DA
Agreed, the DA pull needs a lot of practice but in choosing a "stake your life on" gun, no matter which, I plan on shooting it a lot. I don't want to spread the expense around. I did reload some for the ACP and this is the only time I experienced an occasional jam, usually a failure to feed. Not the pistols fault.
As far as reliability, so far the Colt's plunger tube de-staked after only about 250 rounds when I first got it. This was before I sent it out. It won't run with McCormick 8 round mags, the last round won't feed. In the Springfield, these 8 rounders work fine.
The Springfield has never failed but I haven't shot it as much as the Colt.
When shooting the P97 a couple days ago one mag would eject itself after 2 or 3 rounds fired but it was just that one mag which I took home and cleaned real well, marked it with red tape and we'll see next time.The other mags worked fine.
Ruger mags are easier to field strip and clean than 1911 mags. At least the mags I have. I had one surplus mag come completely apart while shooting. The welds failed. I don't trust mags with welded floor plates so this is another consideration. Even though it probably doesn't happen much.
