SMITH & WESSON M&P-9 2.0 4.25" 9mm 17rd 2 Mags Police Trade In - $319.99

I will never buy anything from this company again a total rip off on stopping an order immediately after buying so say what you want it's pure bullshit

6/15/2026 - Coupon code: "ltkdb_rx4frqbg" knocks $50 off the price. That code is good for 10% off non-excluded items @ DirtyBird ($50 Max Discount per Order). I submitted the code to be added to gundeals yesterday but so far, for whatever reason, it hasn't been added. I don't know when the code expires.

Retay USA RA15-22 .22 LR 8" Barrel 25-Rds Tactical Pistol w/ Folding Brace, Black - $309.99

6/15/2026 - FWIW, KYGUNCO uploaded a short video of this firearm 6 days ago. At this time the vid has drawn only 15 comments.
These two snips from two of the comments might interest some of yall:
-- @edgardomeza2372 5 days ago - "...3 out of 10 mags ran had a few 3 rds bursts ..."
-- @jeremybrown_sc12v 2 days ago (edited) - "Had the gun for 2 weeks. It started running full auto."
Edit: OOPS .... I forgot to include a link to the video. Here it is: https://www.youtube.com/watch?v=W55F-tryJU8...

Dirty Bird AR-15 SMRS Handguard – Slim M-LOK Rail System Gen 3 - from $59.95

That's because it is a "Sale!" item which is "Excluded from additional discounts". That wording is on the product page. Coupon codes can't be applied toward the purchase.

Smith & Wesson M&P Shield Plus 3.1" 9mm (1)15rd, (1) 13rd, (1) 10rd Optics Ready Pistol - $369.99

Was leaning toward a Micro Dagger, but at this price the Shield Plus is an easy winner. In day-to-day carry, the spec diffs will not be noticed. Smith &Wesson wins (again).

I'm trying to buy the 15-in version of this but I'm not getting the coupon price on any of them?

Alpha Foxtrot AF1911 70 Series 9MM 10RD 4.25″ Threaded Barrel Black DLC Polished - $489.99

Too bad it's only a 10 round pistol...and I can't tell but doesn't look like it's optic ready either. Even just with that, this is a great deal. Less than half of other dealers

Retay USA RA15-22 .22 LR 8" Barrel 25-Rds Tactical Pistol w/ Folding Brace, Black - $309.99

I have it in hand but haven't shot it yet. It's definitely AR-style and not a .22 conversion of a milspec AR. It's light, but it feels solid. All polymer except the barrel/BCG/spring/handguard. The barrel is threaded (which isn't mentioned in any of the marketing/spec) with a short slide-over thread protector that gives it the tucked look, but also makes it look a bit goofy with an actual suppressor mounted. The charging handle is polymer but feels up to the task... it also has a comically short pull-to-charge, which makes sense but isn't what you're expecting the first time given the AR ergonomics.

The folding "brace" is also made of polymer but feels relatively sturdy. I put "brace" in quotations because I'm really not sure how it passed ATF muster; it looks and feels like a minimalist stock with "Not a Brace" molded into the butt. I'm moving it over to my 3D-printed dagger chassis and putting an airsoft folding tube and SBA3 on this (repurposing the "brace" was half the reason I bought this).

I've had good luck with the RXP22 from Retay, so I'm hopeful for this one but, unfortunately, don't have any shooting experience to share just yet.
