Received a 28" barrel (JBXPB28) today and played around with it a bit. The 28" barrel looks like it mates up to the 1301 comp pro. The bolt locked in place and functioned properly. In the pictures below, the factory 21" barrel is on the left, the 28" barrel is on the right. With the exception of the gas system, the appear identical.
With respect to the gas system, the 21" factory barrel has both ports drilled out. Each port is roughly 7/64" in diameter (measured using a drill bit as a feeler gauge) and drilled through to the barrel. On the 28" barrel (JBXPB28), each port is approximately 3/32" in diameter, however, only one is drilled through to the barrel. Additionally, the gas valve spring is made out of thicker wire on the comp pro and seems to have an extra half coil or so of length.
I'm wondering what folks thoughts are on the differences in the gas system. I think there is an AR-15 analogy here since the longer barrel will result in a longer dwell time for the gas which is compensated for with a substantially smaller port and an easier to crack gas valve.
Shot it with some factory ammo and it functioned fine, but it did shoot about a foot lower than the stock barrel at 25 yards.
I purchased a 1301 Com Pro with a 24" barrel recently. This wasn't my first choice - I'd actually prefer a 21" barrel to make it more manageable in a home defense scenario, but couldn't find any 21" barrels. And the 1301 tactical either wasn't available, or I just kept getting outbid on.
I guess what I'm asking is, any interest in parting with your 21" barrel? :-)
Second question - if anyone has set the comp/comp pro up in a HD/cruiser ready type setup. Are there any other good options besides the Mesa tactical sureshot side saddle? Am I better off getting a pic rail and shell card separately?
