Build history on GunPartPicker
Builders on GunPartPicker first added the Kriss Glock G21 Magazine Extension KIT 45 ACP + 17 Rd. ALP to a build in September 2026.
Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today all 3 retailers we track have it in stock. The best price drifted down from $29.69 to $22.20 over August 2026 without a real sale. Buying today, the lowest price is $24.66 at KY Gun Company, above August's low of $22.20, so a better deal may come back.
