Canuck63 Posted February 1, 2012 Share Posted February 1, 2012 Hi all, given the absolute lack of LB spares in Italy and Germany I've opted to fit a spare KKM Bull Barrel on one of my LB (a SS Concept V),to bring it to the specs of the other gun fitted with heavy KKM barrels I use in the Italian Championship. As we all know the Concept V comes with a classic barrel with bushing and the front of the slide has been machined wide enough to accomodate the bushing but a wee bit too wide for the front cone of the nbewly fitted barrel. Now...my gunsmith has literally worked on the barrel from the ground up,i.e. he starts from KKMs with an entirely "rough" lower lug area which he reworks with a NC machine. The barrel has a vault-lock feeling to it in the upper lugs area (the slides requires a little effort to hand-cycle it and it needs a push with the thumb to fully lock-up)but has a little "spring play" to it in the front area,i.e. where the original bushing used to be.It's not wobbly like the barrel on a M92 Beretta mind you,in fact it rest on the lower area of the slide and only has a little play upwards when pushed from the bottom (6 o'clock point)of the muzzle.It will immediately spring back to its resting point on the slide. Due to the terrible weather conditions here in Northern Italy I haven't fired it yet (the other guns built by my 'smith with a Caspian "heavy" frame,STI "Choice" slide and KKM barrels that will positively lock on the front part of the slide are tack drivers even after more than 40000 rounds (groupings shots from a rest at 40yards slighter wider than 1.5" are the norm)but I'd love to hear from the "cognoscenti" here if such a fitting would eventually lead to unevenly worn grooves and lugs on the slide in the long run. Since the front part of the barrel will rest on the same area every time the slide locks I doubt that this play ,which presents itself only when forcibly pushing from the lower part of the muzzle,will do accuracy much harm but I'm curious to know what you gents think about that.

tpcdvc Posted February 1, 2012 Share Posted February 1, 2012 There should be zero play when the gun is in battery. ZERO Link to comment Share on other sites More sharing options...

Canuck63 Posted February 2, 2012 Author Share Posted February 2, 2012 Been to the range today to see how the gun would have behaved.Shooting from 25 yds at a 3" dia round target from a rest (a sandbag...not a Ransom)it delivered groups not wider than 1",and the groupings were consistent,always perfectly cemtered and hitting to the sights,apart from the odd flyer,but my sight isn't that good anymore and shooting from a sandbag isn't fun...not if you try to get consistent,accurate groupings!Looks like it will at least hit the A-zone and down the plates!
