I know I'll get plenty of "flak" for this, but...

Three points..

1) While you are shooting a hopped up assailant with those little pills, he may be shooting you with a .40.. Personally I want an attacker down, NOW

2) Extremely limited capacity (unless you are carrying a Scorpion) means you are very poorly prepared for mass attack (Which I have faced 3 times)

3) Bullet tech for the .32 is (as far as I'm aware) still in the stone age. Like the .380 the .32 lacks the energy to both penetrate and expand a conventional HP

I won't carry less than a high capacity 9MM +P with several reloads, and it's been years since I did that.. even my BUG is a KAHR .45

Little off topic. I just bought a new Crvena Zastava CZ999. Not to be confused with CZ from the Czech Republic. It's a Serbian Sig 226 like pistol without the Sig refinements, but a always bang bang type pistol with decocker. The decocker acts as a slide stop as well. This can be had for 289 to low 3's in 9mm or .40. The barrel is chromed lined and chromed all around. As a budget priced pistol, it's full of features and reliable. Comes with 2 mag's. Anyone here familiar or have one? range snow covered from recent blizzard, so no range time yet. you Tube has plenty of vids, and folks seem to like em.

I have read up on them.  Seemed like a good "budget" alternative to a Sig.

I'll have range report later in week. It also has ambi decocker and mag release.

QuoteNotes:
** The 327 federal magnum is reported to make 1300 fps from a 3-1/16" barrel on Wikipedia.  But, this is a revolver which does not include the length of the chamber in the barrel length measurement.  In auto loading pistols the chamber is considered part of the barrel length measurement.  The 327 federal has a COAL of 1.47".  This makes a 3.0625" barrel + 1.47" chamber revolver on par with a 4.6" auto as far as internal ballistics length.

SQL, I thought that the B/C gap in the revolver took away the benefit of adding the chamber and barrel for comparison. You lose pressure with it so any gain you perceive with the overall length is offset by the pressure loss. That's how I understand it and it does make sense.

The cylinder gap does allow for some gas loss, but it's a small part of the reason published barrel lengths about equal in velocity between revolvers and autos. The chamber depth is a greater affect, which allows the same cartridge to discharge at a much lower initial pressure due to the additional volume. Of course, the result differs with cartridge length, bit it doesn't differ much. It's no more complicated than that.

.32 is an ok cartridge... I don't have one because my agency only allows us to carry .380s and above. I love my LCP's size... but HATE feeding it (I now carry a SIG P938 for that reason; also have a S&W 642-1 that I picked up a 9mm conversion cylinder, because my issued sidearm is 9mm).

Similarly, I do like .25 over .22 in a small gun (don't have one, but my father does; Beretta 21A). Centerfire is way more superior to me than rimfire, no matter how good the quality is of the .22.

For breech to muzzle distances over 6" this may make sense.  It is at this distance that you start to see consistent drops in velocity as cylinder gaps get bigger. With breech to muzzle distances less than this, the projectile isn't in the barrel long enough for the pressure loss to gap to have a significant impact.

If you peruse the results at Ballistics by the Inch cylinder gap page for barrel lengths of 2,3 and 4" barrels, you will see that often they record their highest velocity on the .001" gap, not the "no gap" test.  And most of the time the .006" gap meets or exceeds the no-gap.

Thank you, sir. This helps me understand the b/c gap asessment more completely. When i shoot, i look for control and shot placement over power. "If the bullet isn't properly placed, it won't be worth the propellant that sends the projectile downrange". I don't know about you, but my life depends on very bullet that is fired in self defense! If the bullet doesn't find it's mark nothing else matters!

Thank you, brother. Thank you very much.
