Here is something I have wondered about for a while: what good does a bull or cone-type barrel do? How are they functionally better/worse/different than a traditional setup? Do they serve a useful purpose or are they a gimmick?

So what is the point of these things? :grin:

Bull barrels add weight up front, delay unlocking of the slide and barrel which spreads out the recoil impulse over a little more time. People feel they shoot slightly softer with less recoil and muzzle flip.

There is also no bushing to break.

What did I miss? :smile:

If they are so great then why doesn't everybody use them in their custom guns?

Cone barrels provide a much greater bearing area and self-center with zero play for superior lock-up and accuracy. They are also the best way to go for a ported barrel, as the gases do not contaminate the contact area for the slide and barrel.

Check out a Schuemann catalogue/website or Strayer Voigt, which uses Schuemann barrels exclusively, for examples of ported and unported cone barrels.

As noted above, you are elimintating 2 points of potential 'gap' in the 1911.

First is the barrel/bushing contact area. Second is the bushing/slide contact area.

On the bull settup I have on my Pro Eclipse, the slide is solidly pushed against the cone of the barrel. This helps maintain consistant lockup.

The other point that was brought up is bushing failure. This could be breakage or bushing pinch.

It has always been said that Government models are historicly more reliable than Commander models. This is usually traced back to the steeper angle of barrel incline while in rear batery. This can result in the bushing pinching the barrel. The cone/bull system eliminates this problem.

The downside is that a full-length guide rod MUST be used. Some are opposed to FLGRs. I don't dislike them, but prefer the standard system better.

When I eventually build my 'perfect' defensive gun, it will incorperate a bull-style barrel. Both for the reliability and accuracy benefits I see in the system.

I will also look for a solid-end reverse-plug so I can use the standard recoil spring setup. The only problem I forsee is fieldstrip reassembly. The spring will need to be installed before the slide and frame are assembled. It might be a fumbly process, but we'll have to see.

Hope this helped.

CB.....errr... Sean, I was thinking the same thing. They are ALL OVER THE PLACE for the IPSC guns, and with the thought of one less part to break and the potential for even quicker follow up shots, I've been wondering why they are not used more.

Now I'm only on my first cup of coffee this morning, but I think I remember someone (Larry Vickers?) giving the cons of a bull barrel in a combat pistol. Or maybe I just need more coffee :grin:

How much weight do a bull barrel and FLGR add to a 5" pistol compared to a conventional barrel with bushing and GI-style spring guide and plug?

How long does it take for the forward barrel-to-slide fit to loosen and what do you do when it does? (Obviously, you can't just fit a new bushing.)

Does anyone know if the bull barrels in 5 inch are in the proposal stage to be approved for IDPA. I know the 4 inch guns with the bull barrels are approved.

I have several folks who like them in their guns both four and five inch barrel length.

Full length guide rods MUST be used with bull/cone barrels? I'm new to shooting, but my CQB compact has the short guide rod with a reverse plug. I might have my terminology mixed up.

I hope your not kidding Sonet.

I have been looking for a solid-end, Commander-sized, reverse-plug for 5 months. I would be using it on my Pro Eclpse. It has the same slide length as your CQB.

How long is the spring-guide stub on the other end of the spring?

How is it disassembled?

This was the system I was talking about at the end of my last post. If Wilson has the parts it'd be great.
