Bar-Sto barrel question

I am looking at a 9mm conversion barrel for my P229 and I see many of you have used them.How many of you had to fit the barrel? and what area of the barrel possibly needs to be fit?

Honestly, if it were me, I would buy the match target barrel and have Robert Burke fit it.
You can so very easily take off too much if not careful.
It's just really important to have it fitted correctly.
Reason I say this, is because Burke told me.

I bought a semi fit Barsto barrel and it still needed some fitting for my P229. But it's very accurate. Fitting instructions are included but I had a gunsmith do it for me.

My other EFK Fire barrel required no fitting and is less accurate than the Barsto, about the same as OEM.

They are both very reliable with no issues. Thousand rounds thru them with 9mm recoil spring and magazine.

If you just want to simply convert your P229 to 9mm, I'd get the EFK one because it's cheaper and requires no fitting. If you want absolute best quality and accuracy, go with Barsto. They both have 2-3 month wait time though )

The Bar-sto barrel for my P224 required fitting but Iím not sure exactly what areas needed filing, because like @sigken, I had a gunsmith fit the barrel. It was an extra $20 and about 20 minutes well spent, because he did a great job.

EFK for my 229R 40 was a drop in. The Barsto semi fit for my 229C (224 slide) took me almost 2 hours most of time was on bottom of feed ramp (~0.020")

For me I hand fitted two Bar-Sto P224 9mm conversion barrels; took some Arkansas medium and ultra-fine stones, filed under the feed ramp and on the sides of the barrel hood. Took about an hour. These areas were obvious to me because 1) the hood would not fit into the slot on top of the slide (too wide); 2) the bottom of the feedramp was catching the top of the locking insert, preventing the slide from being pulled all the way back. Go slow and recheck fitment frequently.

Note that Bar-Sto and others are 1:16 twist and not 1:10. I bought a Bar-Sto and fitted it
to my P-226 9mm. It shot high and to the right. Grouped just ok with 115 grn but was horrid with 147. Sold the barrel and wouldn't buy another. Had my factory barrel reverse crowned and 300 degree cyro and it can shoot 1/2" groups standing at 7yds

Drop in, and Match include in some cases, more than the outside dimensions, and Match grade may require headspace reaming, once fitted.

Normally fitting the barrel into proper "lock up" into the slide's ejection port is all that is required, with a "Drop-in". If you had an "alignment gauge" to insure the "firing pin" was located in the center of the bore line, you would probably be "complete". Many times material is taken off the bottom, when unnecessary, if barrel properly aligned.

Check the videos, in the Gunsmithing "sticky" section, to see what is involved.

As already mentioned, care should be taken, as once you "remove" metal it can't be replaced... and you end off with a looser fit. If you don't have patience, then as others suggest, let a professional handle the job.

I bought a Semi Fit BarSto 9MM for my P224 and it required a little fitting. Would not drop in. I'm used to doing this from my line of work so it wasn't difficult for me. I measured and found I had to remove about .001" from the edge shown in the picture. Only took a few minutes and it dropped in nicely.
If you're not familiar with doing this type of work I would strongly suggest having someone that is do it. Like others have said, you could wind up with something pretty useless.

to eliminate any conversion barrel issues-

Purchase the appropriate 9mm Para Caliber X Change Kit for your P229 from SIG SAUER or one of the distributors.
