    Hey all.
    Quick question. One of my shooting buds back home is getting his CCW and he’s looking for a nice carry pistol. He asked me a question about the SIG pistols and I didn’t have an answer for sure so I told him I’d find out.
    Apparently a local shop he goes to has access to P229 in 40 S&W and in 357 sig. These are police trade in pistols and the price agrees with my buddy. The thing is that he wants 9mm. He asked me if the P229 pistols in 40s&w and 357sig can be converted to 9mm easily and SAFELY without too much expense. I think he is thinking that it could be done like the Glock 23 or 27 and just drop in a barrel and you’re good to go.

    Whats the scoop? Is converting them possible and if so, is it a safe and simple conversion or is it a costly proposition??

    thanks all and gave a good week.

    I have the 229 in .357/.40 and yes it is possible to also convert to 9mm.
    There are Sig brand p229 slide and barrel kits out there but cost several hundred and are hard to find.
    Alternatively there is a Barsto 9mm barrel that can be fitted in the existing slide, but will need a 9mm 229 mag and spring. That barrel is $240.
    Probably cheaper to find a used 9mm 229. Or use the .40 which is what the 229 was designed around.

    Possible yes but I’ve done the math and it’s not worth it.

    I sold my .40 P226 and bought a W German P226 in 9mm for cheaper than the conversion barrel, 3 mags and springs.

    The Barsto barrels require fitting, so getting a used one is potentially a big waste of money.

    That's not true at all.

    What your buddy wants to do makes no financial sense. He is being blinded by the lower price of the unwanted 40s. Buying a cheaper 40 caliber pistol and then buying a 9 mm barrel will end up costing much more than just buying a 9 mm pistol to begin with.

    My 229 in 357. My son converted it to DAK and added E2 grips.

    They are harder to find but LE trade-in 9mm 229s and 226s do hit the market.

    Bought one from Aim Surplus last year.

    The Sig .40 and .357 barrels and mags are interchangeable in the 229. The 9mm Barsto barrel MAY need to be fitted (very minor operation). I would recommend an adjustable rear sight or know the POI shift with the different calibers. Also note the p226 mags with xgrips also work for additional capacity.

    Thanks for the info. I’ll pass it on.

    I took it that the 40 version of the P229 was around $375 or so. Like was said, I think he thought a conversion barrel could be bought and used for about $100 or so, similar to GLOCK conversion barrels.

    I didn’t know LE trade in P229’s in 9mm could be bought that inexpensively. I always see them in the $600’s.

    Thanks again all. larry
