After Market Barrels

[40SWHero51]

Did a search for "after market barrels" and didn't find anything worth while - although I didn't dig too deep either. Please paste an old thread if you know of a helpful one.

Question:
Are after market barrels as good as they are made out to be?

I am getting ready to pickup a Storm Lake 9mm Semi-Drop-in Conversion barrel for my .40 S&W M&P to shoot a little cheaper at the range. However, I have read and heard that after market barrels can perform better than factory barrels in most cases - yielding tighter groups and less mis-feeds. And for all you "Glock Heads" I have read that this is particularly true for your guns of choice.

For $98 plus the cost of a new magazine I can turn my rig into a 9mm for range use - and keep my beloved .40 for Defense/Carry. Before I buy the 9mm conversion should I also look into replacing the factory .40 with a Storm Lake barrel as well? I say Storm Lake mostly because it's all I can really find for a S&W M&P.

Let me hear what you got on this...

On an unrelated note:
What is "bonded" ammo - rather what makes ammo "bonded" and what good is that to me?

Thanks.

Is there something more than just the barrel and mag change to
9MM Luger from .40 S&W? I'm curious as to how the smaller
diameter case is 1) supported and 2) extractor hookup?

I have an aftermarket barrel from Jarvis Inc. It's for my 1911
I haven't looked at the other options Jarvis offers
except I know they offer a Glock model - mentioned it to my
shooting buddy who has a G19.

Have you found any aftermarket barrel makers for CZ's ? I'm not
really in the market for one, just would like to know if/when barrel makers
start supporting CZs.

Bonded means the bullet maker has figured out a way to
ensure the Jacket doesn't seperate from the core - beullet
weight retention/integrity.

You know - I hope there isn't much more to converting my M&P to a 9mm than what I said - because if there is I am in trouble. I cannot find any info on it anywhere on the web. I have read how easy it is to convert Glocks to pretty much any other caliber that Glock makes, but am unsure about the M&P.

Is there anyone out there who can help me with what else might be needed for this conversion?

BlindJustice:
As for an after market for a CZ have you tried EFK or thegunsource.com - thegunsource.com has a lot of CZ selection and maybe the barrels to match.

Some people like the change the extractor. Personally I just have a mag and barrel for my G22. I have never had any issues. I have two after market barrels for my G22 they are usually more accurate because of a tighter fit. Jarvis makes a very good barrel but I wouldnt pay the price they are new I picked a new one off ebay for 125 before they stopped selling gun parts. My conversion barrel is a Lone Wolf G35 conversion barrel. It is an inch longer but functions fine and looks kind of cool especially with a 33 rd mag.

I have heard it is quite easy to do pretty much anything to a Glock. I am figuring that all I need for my M&P is a magazine and the barrel. Another hump to get over is that the barrel is semi drop-in not drop-in. There may be a need for some fitting - according to Storm Lake in most cases it functions as a drop-in. We will see how it goes when I make the conversion purchase.

 

[Seafarer12]

You will have to let me know how it goes. I have thought about getting an M&P but havent because of the lack of aftermarket unlike the Glock. A 40 to 9 conversion might be enough reason for me to sell all my Glock stuff and buy a M&P.

Thanks

Thanks for all the input.

I have a 9MM conversion barrel for my XD SC .40. That and a mag are all it takes. It does not seem to have any problem extracting or ejecting, and besides, its for range use and cheaper practice/fun, not for carry.

Sometimes, all you need to do to convert .40SW mags to 9mm is to change the follower in the magazine. If you do it this way, you may discover that a 10-rd .40SW mag suddenly becomes a 12-rd 9mm mag.
