Something to make your Glock 17 or 19 airsoft pistol look even meaner. This Building Fire Compensator for the Glock 17 and 19 costs US$20.99 at RSOV.com. Problem in the product description is what brand of such airsoft pistols will this be compatible with, otherwise some modding will be required. Better enquire first at their website to ensure that your Glock is compatible with this before placing an order.
