There are never too many accessories for Glock (subjective opinion of the author) - VFC probably came with a similar assumption, signing a license agreement with Fowler Industries, which specializes in making of accessories for the above-mentioned pistols, including slides, barrels, frames and triggers.
The company has licensed the Vega Force Company to produce airsoft versions of the Mk 1 and Mk 2 model slides with dedicated Zero barrels and triggers.
The new VFC slides for the Glock 17 and 19 feature aggressive ribbing for easy slide pulling.
The release date and price of the new accessories have not been announced yet.
