Yes, it's feasible. The only advantages a .38 snubbie has over a "baby Glock" (G26, G27, or G33) is lighter weight, and a simpler manual-of-arms (instructions for use). The baby Glocks are about the same size as a S&W J-frame 5-shot snubby (see photo below), are a whole lot easier to shoot well (especially rapidly), hold twice as much ammunition, are MUCH easier and quicker to reload, and can use the magazines from the larger Glock models in the same caliber for reloads (you can use a 17-shot Glock 17 mag, or a 15-shot Glock 19 mag to reload your G26; all are 9mm caliber, and the longer mags will fit and function in the shorter guns). The Glocks are heavier, but not unmanageably so, and given their double ammo capacity of the snubby and ease of shooting, most folks think the weight increase is a fair trade-off.
