    Yeah, I make fun of the newer style guns from time to time, but i love 'em all. I'd even consider getting a Glock I guess after 15+ years any rookie can be proven.

    Iv'e heard you shouldn't shoot cast bullets w/o a bbl R2?
    Also i have a brochure, there is a "357" is this the 357 SIG?

    My Glock would be in 9mm since i have .45 in 1911 as it should be! Aw come on smile! I admitted to possibly liking a Glock.

    PS
    I like the look of the Glock adjustable rear sight. Feel free to help me part with my paycheck.

    your gonna get a lot of opinions on the lead thing. glock says dont do it. ive heard bad things about some glocks having problems with lead, but my brother has two glocks and weve put several thousand rounds of lead through them both. so if you do it approach it with caution, checking frequently to make sure the barrel is not excessively leading.

    Glock seems to be inconsistent in the answer. They now say no lead, but my older models manual says its ok. I have seen frequent posts about how it gums up the rifling, though. I wouldn't do it.
    357 does stand for .357 Sig. High velocity round similar to .357 magnum w/125gr loads. You can drop a .357 barrel in a .40 to convert it and vice versa. You can also get aftermarket barrels that will shoot lead fine.
    What model depends on purpose. For carry, fun, target, or home defense? HTH-Peter

    I can tell you from personal experience NOT to shoot non-jacketed lead bullets out of your Glock. I posted on the old board about a problem I had with my 23c after just 50 rnds of lead reloads I fired through it. I recieved lots of very useful feed back from some extremely knowledgable folks. The bore was completly covered with fouling; it appeared to be smooth. This will cause overpressurasition and possibly a blowout! It honestly took two brand new bore brushes and over an hour to clean the barrel alone. Just something to think about.

    When I was in Glock Armorer's school we were told never to shoot lead and to report any Department Glock we saw with evidence of lead being shot. The Department I do armorer's work for has experienced several KB's with the Glock 22 just on remanufactured ball .40S&W. I own a Glock 30. I immediately replaced the barrel with a Firedragon match ported barrel to prevent this, but any quality barrel with lands and grooves will suffice. A Glock KB is nothing you want to experience... can do real damage to your hands, arms, and face. Not a goood day...

    Convinced, Thanks.
    As a general rule i try to follow Mfg's recomendations. I didn't get a chance to querry Glock. I can live with jacked only untill i can get around to an upgrade. Got firedragon, any other bbls aftermarket for Glock that safely sling lead?
    I am also intrigued by the .357/.40 conversion option. thanks for the heads up on that.

    I got around this with my 23 by getting an Olympic Arms replacement barrel. I have shot a significant mix of lead and FMJ through the gun since with no signs of any problem. I shoot lead reloads almost exclusively in my handguns for the financial savings, so I planned on a new barrel when I bought the Glock.

    Brownells has a lot of aftermarket barrels for the Glock that safely shoot lead. The reason I went with Firedragon was velocity. If you switch to a standard length replacement barrel with lands and grooves you will lose 5-10% velocity as compared to the Glock barrel and according to the load you use. The Firedragon barrels are 1" longer than standard and are ported. It brings the velocity back up due to length and in turn, the porting keeps the muzzle down. Medicine Bow is the new Firedragon middleman to the public. Do a search on Dogpile and you will find them, as I don't have their # at this time.

    This is going to sound dumb, but here it goes!!!

    I thought all rounds where made from lead. So what brands of ammo are good for target practice? I'm using Gold Dot for carry is that ok to use?

    Thanks

    gold dot is a professional grade projectile and should sufice as long as you are comfortable and shoot it well. no such thing as a dumb question. In a funny way most rounds are made of lead in the core anyway. some just wear different jackets and designs. then you have cast lead. this is melted, poured in molds, sized and lubed. usually a mix of lead and tin. wheel weights are a good example as well as commercially sold "lead" the other is swaged; kind of like a rod of lead cut and cold formed into the shape of a bullet, normally has some sort of lube as well. this hardly explains everything, very much info omitted due to space, hope it helps.

    I don't have a Glock and probably never buy one because of the LEAD problem. I do a lot of indoor shooting where they require lead only. I have a Browning Hi-Power 9mm and it was leading and keyholing. After slipcasting the barrel, I found the barrel to be 0.3585". The bullet diameter from SAMMI is set to 0.355" for the 9mm bullet. In a couple of reloading hadbooks state that a correct barrel diameter for a 9mm should be 0.354-0.356". I called browning and the told me there tolerance for the 9mm Hi-Power is 0.355-0.359" and they said that the barrel wasn't designed for lead bullets. Which I believe is a very poor excuse. I would be curious to see what the tolerances on the glock barrels vs. the bullet diameter size is. Jacket bullets don't have this problem in barrels at these tolerances because they harder and have a jacket to hold the shape of the bullet in the barrel. I feel (and this is just my opinion) that if a barrel was correctly (a tolerance that matches the standard size of the bullet), then the barrels would have no problem shooting lead bullets. These companies are doing this just to save a couple of pennies. Buy the way I bought an aftermarket barrel for my Browning Hi-Power for $75.00 and it doesn't lead up and shoots very accurate. $250.00 for a CRAP barrel from Browning. Never buy a Browning product ever again PRICELESS.

    I don't think the glock lead issue is because of barrel tolerences. I'm not an expert but i think it is because of the polygonal rifling of the barrel. the up side of this rifling is greater velocities and accurracy w/jacketed bullets. I don't know exactly how, though.

    I have also heard it lies in the Polygonal BBl in Glock's case. I would also appreciate hearing the expert explanaition of the BBL sytle as I don't know the details.

    The octagonal and hexagonal rifling in the Glocks is hammer forged as opposed to cut like barels with lands and grooves. This makes for a tighter bullet to barrel seal which means less gas escapes from behind the bullet which means the bullet goes a little faster.
