What I'm looking at is how well the convertible aspect works in real life.
I'd suspected there'd be a lower level of accuracy in shooting the ACPs, with that relatively long gap between ACP case mouth and the internal chamber constriction set up for the longer .45 Colt, and so far my testing has confirmed it in these two samples.
Some of us want to know what we can expect from the ACPs.
If I'm getting 13-inch groups with one load, that's not practical.
If a second gun sample takes that same load down to 9 inches, better, but still not really worth bothering with.
If I get two or three ACP loads that'll run inside 4 inches, while the rest are up around 6,7 & 8 inches, that gives me useful info in deciding whether or not the ACP option is viable.
Tells me the concept IS viable, but picky about ammo.
Limited sampling has uses, but larger sampling gives more valid results.
Not knocking your enjoyment at all, but your definition of "Shoots good" may differ from mine, and my definition of "Shoots OK" may differ from yours.
Quantifiable data helps us all compare to see how the model fits in our own shooting world.
I understand not everybody wants to go through the hassle of shooting for strict accuracy.
Hoping somebody else might.
