Yes. The Lone Wolf Arms AlphaWolf Glock 27/33 9mm Conversion Barrel will work for the Glock 33 (Gen 1-4). It will function best when using magazines designed for the Glock 26.
I do not trust unbranded Glock conversion barrels so it is worth it to me to buy the Lone Wolf ones as their stuff is flawless. It slipped right in and is a quality item. Fitment and materials are spot on. I just added an OEM 9mm mag and I have a mo...

Pleasantly surprised. Clean look, very little seated round movement and superb feeding. Love the fluted barrel. The weapon, a G27 Gen2.5 was an LEO purchase in 1996 so I was a bit concerned about the cycling. It cycled flawlessly, even with the G19...

9mm is cheaper than .40 right now. I originally wanted to trade my G27 for a 26, but I found this Conversion barrel and decided to get it. It fits and functions great. Some people say you need to change to a 9mm ejector and extractor, so I went ahea...

This conversion barrel works great in my Gen 3 glock 27. I have shot 50 rounds through it with no issues. If you want to convert your Glock 27 to a 9mm, this is a great option. For me it shoots very smooth and from 15 yards in very accurate.
The 9mm conversion barrel was exactly as described. Purchased this for the conversion of my Glock 27 and it fits flawlessly. The entire transaction through Optics Planet was smooth. The delivery was very quick.
Product Info for Lone Wolf Arms AlphaWolf Glock 27/33 9mm Conversion Barrel
Replacement barrels establish the benchmark for absolute accuracy and combat reliability. Because barrels are the most susceptible component of a gun to wear and tear, they wear out, they get scored, they get dropped in, and can get dropped out and installed back in just a few shots. At Lone Wolf, we spend a great deal of time figuring out what barrel designs will fit a particular gun and meet the customer's needs. It is our goal to make the Lone Wolf Arms AlphaWolf Glock 27/33 9mm Conversion Barrel fit that particular gun, drop in, super easy to install, and have the customers satisfaction that they were made for drop in swap outs. Using a drop in method, the barrel is a drop in that just drops in and drops out. Ease of installation is amazing as it just drops out and there is no bedding in or fitting required. Simply open the barrel, remove the old barrel, put the new barrel in and ... drop in. No fitting needed as its a drop in that just drops in and installs like any other barrel. Lone Wolf Arms 416SS barrels are button Rifled, three stage honed, and three shot honed. Salt Bath Nitride (SBN) coating drives out more gas and fouling. Provides a permanent, rock solid, non-leak tight bore that is engineered to consistently shoot flat and accurate. Fluting on the barrel's interior and exterior provide an excellent method for heat and debris to escape the barrel. AlphaWolf barrels are coated with several thousand linear feet of salt bath nitride (SBN) coating that is extremely resistant to abrasion and corrosion and provides a minimum of tenaciousness in the barrel.
