Radial Appendix Carry Holster for M&P Shield Plus - Sidecar

In this review of the Radial Appendix Carry Holster for the Smith & Wesson M&P Shield Plus 3.1 in, the bottom line is simple: this is a purpose-built appendix sidecar for Shield Plus owners who prioritize concealment and modular adjustment. The reviewer found it to be especially strong on concealment thanks to an adjustable claw and a magazine ridge that reduces printing, while the dual pocket clips and retention adjustments let users fine tune ride height and cant for daily carry comfort. It is designed only for the Plus model and is not compatible with lasers or lights.

Key Features

• Fitment: Molded precisely for the Smith & Wesson M&P Shield Plus 3.1 in 9/40 to ensure a secure, repeatable draw and passive retention.
• Fully adjustable: Retention, ride height and cant are user adjustable so carriers can set a consistent position and preferred draw angle with the dual pocket clips.
• Maximum concealment: The adjustable concealment claw pulls the grip tight to the body and the magazine ridge reduces printing for a flatter profile under clothing.
• Accessory ready: Suppressor-height sights and optics fit without modification, allowing common sight setups to be carried as-is.
• Material and build: Made from premium 0.08 kydex molded to the firearm for durable shape retention and long-term service life.
• Warranty: Backed by a no BS lifetime warranty that covers repair or replacement if the holster breaks.

Who It's For

This holster is aimed squarely at owners of the Smith & Wesson M&P Shield Plus 3.1 in 9/40 who want a dedicated appendix inside-the-waistband sidecar solution for carrying both pistol and spare magazine. The design benefits daily carriers who value concealment and the ability to dial in ride height and cant for body type and clothing choices.

Those who should look elsewhere include shooters with non-Plus Shield models, users who require laser or light compatibility, or carriers who prefer belt-only holsters instead of pocket-clip appendix rigs. If you use a light or a laser on the handgun, this model will not fit.

Pros & Cons

Cons

• Only fits the M&P Shield Plus 3.1 in 9/40 model and is not compatible with lasers or lights, limiting versatility.
• The pocket-clip appendix style may not suit those who prefer belt-mounted holsters or carry positions other than AIWB.
