Eight reasons: [1]Using the Rem .38 LSWCHP +P, I don’t need 2 types of ammo, (one for my 4” barrel and one for my 2” barrel). [2]The Rem .38 LSWCHP +P is all soft lead with no copper jacket so in a Snubby I don’t have to worry about will it or won’t it open due to velocity. [3]SPLAT! that soft lead either opens up big and wide or even if it don't open it will flatten out bigger and wider than a failed copper HP will. [4]I don’t like being lied to; Speer says “Our 38 +p 135 gr Short Barrel EXCELS THROUGH FBI PROTOCOL TESTS”. Actually 11”of penetration in bare gel is 1” LESS than the FBI minimum so no “EXCELING” there and I would hardly call 13” penetration in the IWBA Heavy Clothing [denim] “EXCELING”. I called Speer and asked them: Why did it penetrated more in the denim test than it did in the bare gel test? Their answer was “because it failed to open up in the denim”. Huh! [5]The Rem .38 LSWCHP +P has a long successful track record, it was the first hollow point. [6]That big 158gr hunk of lead gets the job done. Several lesser reasons are, [7]The Speer .38 +p 135gr Short Barrel costs 40% – 50% more than the Rem .38 LSWCHP +P. [8]Even if somebody wants some Speer .38 +p 135gr Short Barrels, there has been none available for the last 3 months. Good luck
